Time: 10:00am-4:30pm (9:00am start setup)

Summer Social + Vanatoo visiting us!

Time: 12noon-4:30pm

Place: Mercer Island Congregational Church

We will start the event earlier than the usual club meetings. Great opportunity to meet and socialize with fellow members. We have a packed agenda.

• Potluck style: We will provide hotdogs, pulled pork, sandwiches, light snacks, drinks. Bring your food and drink selections to share with other members.
• Swap table: Bring your audio gear you want to swap or sell.
• Vanatoo visiting us! Details below.
• Vote for club cabinet build.

Regular meeting agenda:
1. We are excited that our very own club member Gary Gesellchen of Vanatoo ( will join us for a presentation about his unique approach to speaker designs and demo of his award-winning speaker line up. Gary graciously donated a few of his great sounding speakers to the club which we will auction. This is your chance to listen to the T1E pair that was also reviewed by Jason Victor Serinus in a recent issue of Stereophile, and bid to own them while supporting the club:

Here is in Gary’s words:

• I'll bring a set of our new T1E's (Transparent One Encore) for demo. This is actually the same set that Jason Victor Serinus reviewed for Stereophile.
• We are willing to donate a set of T1E's to the club for auctioning off. This will be a set that has had the box opened but is in like new shape. They normally retail for $599 (or $529 for an open box), so hopefully someone will be willing to give the club several hundred dollars for them! Here’s the link for more information:
• I'll also have the set of passive cherry T1's I brought by last time that I can give to the club to sell. They’re probably worth ~$100.
• I have a box of speaker parts that aren't current production that I'd be happy to give away for club benefit and auction or donation. A few woofers, tweeter, and PR's.

2. Vote to confirm club’s additional cabinet build, which will cost up to around $750 materials and no labor cost:
• We will build a modular cabinet with 3 sections and deadlocks, to hold our club equipment and speakers. This will help to make our setup and teardown easier and faster, as well as providing an additional secure storage. Please plan to join the summer social as we will vote after 1:30PM.

Jaguar Audio Designs of Bellevue Visiting the Club

Time: 1:00PM – 4:30PM

Place: Mercer Island Congregational Church

NOTE: • Bring your own vinyl/LP’s and digital music sources (CD/USB/DAC/etc…)

• Club annual dues are due. Please remember to bring your due payments to the meeting.

• There is a change in plan; Atmasphere will not be able to visit us. Instead, we will host Jaguar Audio Design of Bellevue. This is bound be a another great event that we will experience analog and digital sources, and compare the formats. Don’t miss it! 

Bellevue’s will be presenting two products from the brands they offer:

• La Voce DAC from Aqua Acoustic Quality

• Runwell Turntable from Shinola. 

Aqua Acoustic Quality is an Italian designer of digital converters. The Aqua house sound can best be described as hypnotic and musical; as DACs go, Aqua generally falls in the same camp as the DirectStream or Lampizator (as opposed to more digital sounding DACs). Aqua makes three DAC models, the La Voce, La Scala and Formula. The Voce is the least expensive model and biggest bang-for-the-buck option, at just under $5K.  From the Aqua Website “Designed to provide absolute modularity, the La Voce S3 is a pure R2R ladder - FPGA-based DAC without digital filter. It has a sign-magnitude ladder converter. The absence of digital filtering means no processing of the input signal. The original digital samples are translated to the reproduced sound, preserving the transient shape and avoiding any ringing. In this way we also avoid the ‘intersample overs’ problem that is vital to faithful reproduction, considering current recording studio practices. With our R2R conversion technology the sound is natural, fast, dynamic, and without the sense of compression characterizing others converters.”  Detailed technical specs can be found here:

Shinola products are designed and manufactured in the USA, Detroit. The Runwell turntable design is quite retro and the manufacture quality is superb. This relatively compact unit contains quite a bit of machined aluminum and weighs in at around 35lbs. At $2,500, the Runwell comes equipped with an internal phono preamplifier, Ortofon cartridge and VPI-designed tonearm. This all-in-one, plug-and-play orientation is not targeted at the tweaker audiophile who wants to experiment with different cartridges, tonearms or phono preamps…it’s more for the music enthusiast who wants a high level of performance and just wants to plug it in, collect records and listen. You’ll find the sonic performance of the Shinola Runwell’s turntable is as stunning as its looks.

If you wish to donate part of your sell to the club that would be greatly appreciated as we are trying to save for a new amp. This is one of the funnist meetings of the year and a chance to get to know everyone better so we would love to see everyone there.    

Aug 22nd 2015 - Doc Bottlehead- Meeting will include some short presentations by Dan, headphone listening stations (also featuring the new “Neothoriator” headphone amp using 845 tubes driving AKG K 1000 ear speakers!!!), and a lot of great music from the custom multi-amped audio system in Bottlehead’s main listening room. Bring your significant others for a beautiful road trip to hear some great music on Bainbridge Island. Soft drinks and snacks will be provided, with stronger beverages available a few steps from the venue. Because of the location for this meeting, the meeting will be held on Saturday August 22nd, 2015, from 12-4pm. Bottlehead is located at 9415 Coppertop Loop NE, Suite 101, Bainbridge Island, WA 98110. It is approximately three miles from the Bainbridge Island Ferry dock. Most of you will be taking the ferry from Seattle, or as the locals say “the boat” to Bainbridge Island. We will discuss this at upcoming meetings, but think about carpooling, ridesharing, or even renting a van or two if there is enough interest. This event will constitute the regular August meeting for PNWAS – there will be NO meeting on Tuesday August 11 (our normal meeting day).  

June 9th 2015 - 3beez - Jeffrey Barish, founder and president of 3beez, will give a two-part presentation to PNWAS. The first part will be based on his article in the current issue of The Absolute Sound (issue 253) called “Understanding Digital Music Systems”. This portion of the presentation will address issues that confuse and intimidate many newcomers to computer audio, particularly the inaccurate and inconsistent terminology used to describe products in this category (including the term “computer audio”). A simple set of terms accurately describes all digital music systems. The presentation will continue with an open discussion of other issues related to digital music systems. Bring questions.   

The second part of the presentation will be a demonstration of the Wax Music Management System (winner of a 2015 TAS Editors' Choice Award), the product that Jeff originally designed to rip, organize, and play his own music collection. You will see and hear Wax Box 3, the latest version of the product, which has not even been announced yet. Many users comment that the Wax software is the first to solve the "classical music problem", but lovers of music of all genres appreciate the ease of use and flexibility of the software. 3beez's custom software makes it easy to catalog by work (rather than track), to survey a music collection (rather than search), and to preserve information that used to appear on the record jacket or in the liner notes — even by users who lack degrees in computer science. Ripping a CD collection is usually a big project, but with a system like Wax, the end result amply rewards the effort.   

Dr. Jeffrey Barish is founder and president of 3beez. Prior to 3beez, he was founder and president of EuPhonics, a software firm specializing in audio and music synthesis products for the computer and professional audio industries. At EuPhonics, he invented many signal processing and system architecture innovations, including a fundamentally new music synthesis technique based on spectral modeling which produces very realistic instrument sounds. During this period, he was also a professor of electrical engineering at the University of Colorado at Boulder. When 3Com acquired EuPhonics, Dr. Barish became Director of audio technologies for 3Com. Prior to establishing EuPhonics, Dr. Barish was founder of Sonic Solutions, which introduced his NoNoise system for eliminating noise from audio recordings. Earlier in his career he was hardware manager at Lucasfilm/The Droid Works of the team developing SoundDroid, a programmable system for processing digital audio. Dr. Barish has a PhD and MS in Electrical Engineering from Stanford University, and an SB from MIT. His doctoral dissertation on concert hall design established design principles that have been applied in concert halls around the world, including Symphony Hall Birmingham, England and Harris Concert Hall Aspen, Colorado. Dr. Barish was awarded a Fellowship by the Audio Engineering Society for this work. He also served on the review board for the Journal of the Audio Engineering Society for many years.  

May 12th 2015 - Rockfest - We will be having our own "Rockfest" in May. All participants are encouraged to bring in selections of their favorite type of rock; blues, country, classic, funk, hard, jazz, progressive, punk, rockabilly, roots etc.. As an additional twist, we want to find some new gems. We have all heard the Beatles, Led Zeppelin, Pink Floyd, etc., so bring in some music (vinyl or cd's) that may not be familiar to rest of the members. We will try and accommodate two or three songs per individual depending on our turnout. Please feel free to share any information you may have on the artists with the membership. It should be a fun and entertaining evening!

March 10, 2015 – It's Polish Night at the next meeting of the Pacific Northwest Audio Society! Forget about kotlety mielone and pierogi, we're going to take you on a journey with Polish DACs! First, we're going to be exploring the new Mytek Manhattan DAC. Designed and built by Michal Jurewicz, we're going to explore all its features and listen to the wonderful DSD music it can provide. After the break, we're going to delve into the Lampizator DSD DAC by Lukasz Fikus. His purely analog DACs defy imagination. We'll listen to both DACs through an EMM Labs Switchman 3 to see if we can even the playing field. Should be a great meeting for anyone wanting to move up into the ever-growing popularity of hi-end DSD DACs.  

February 10, 2015 - This month, we will be playing vinyl on the club turntable. Our Rega P5 has recently been modified with a new Groovetracer sub platter and bearing , and a new Groovetracer delrin platter. Both are a nice improvement, and if you have not heard it please check it out. We encourage you to bring one or two favorite records that you would like to share with the club.   

January 13, 2015 – A very informative and educational evening. Bring a friend or family member. We are honored to have Gary Dahl and Robert Trainer as our speakers.

We may even get to hear music being played on the baby grand piano!   

December 9, 2014 – Our annual holiday social event. It will be a time for conversation and interaction between club members. We are encouraging folks to bring any analog or digital music that you really enjoy, which may not be widely known by the membership. In addition, there will be tables set up for an informal swap meet to find a home for those items that have been taking up space in your closet or drawer. Please bring any signage for your items. The club will be providing food and beverages for this event and are requesting a monitory donation to help defer the cost. We hope to have a large turnout for this meeting and look forward to the music, camaraderie and conversation!   

November 11, 2014 – As part of our settling in to our new digs at the Women’s Club in Kirkland, we will be investigating the effects of acoustic treatments deployed in various configurations. To do this, our own Joe Pittman will be facilitating and orchestrating the placement of acoustic treatments around the room, then all of us will listen and judge the results. We need your help to do this. We need your ears and your opinions, and we need your arms and legs to help move things around. Don’t worry (be happy), it won’t be all work. Joe will be providing tunes from his server with playback through parts of the club’s reference system with some notable guest equipment appearances.  

October, 2014 – 

September 11, 2014 – Our meeting will feature most of the entries from "The Puget Sound! DIY Speaker Contest" which was held last month! It seems that each time we hold the Contest, the quality of the entries improves and this time was no exception. One significant difference were the number of three-way speakers that were entered. A total of four entries were 3-way designs! There have been several times in the past when there weren't any three way designs entered at all. There were also several 2-way speakers that sounded quite nice, as well. We believe that you'll be amazed how well these speakers actually sound in the Club's system. We also intend to have as close to the same system as we used in the Judging Room. This is one of the fun meetings where you can see what some of the members have been doing.  

August 14, 2014 – The Audio Society and the Seattle Head-Fi crowd team up to welcome Doc Bottlehead and Clark Blumenstein (of Seattle’s Blumenstein Audio). Doc has just a released a new DAC kit that sounds amazing and Clark has been working on a new floorstander design. If you love high-sensitivity speakers with tubes or headphones, this promises to be a banner meeting. This event will start a few hours early (5:30pm) for a mini Head-Fi meet (we'll also have an extended mid-meeting break to explore headphone setups). We expect to have some very advanced headphone setups on hand, so show up early to take advantage of this opportunity to hear them.   

July 10, 2014 – Our annual summer social event and BBQ! This year’s party will be held at club member and former club president Andrew Kosobutsky’s house in Newcastle, WA. Andrew has a wonderful listening room and will be spinning vinyl (and digital if you insist) from his extensive collection strictly for our listening pleasure. This event is one of the most enjoyable events of the year. Don’t miss it.  

June 12, 2014 – Phono Preamps   

May 8, 2014 – Our May meeting will feature a presentation of the new PS Audio DirectSteam DAC. This DSD-capable DAC is the brainchild of Ted Smith, a longtime friend of PNWAS, and now lead designer for this product. Ted presented an early prototype of this unit some three years ago. We liked it (a lot) then, and look forward to hearing the production version.  

April, 2014 – 

March, 2014 – 

February 13, 2014 – Album Covers – Our February meeting will focus on music, mostly new music, at least new to many of you. You will likely recognize the track title, but the artist and the style will likely be someone and something you’re not expecting. We will be presenting interesting covers of music in several genres, whose original or popular version you likely have in your collections. Fun stuff, representing possible additions to your collections.  

January, 2014 – 

December, 2013 –

October 10th, 2013 - Buying vinyl, either online or in a record store, is a bit of a gamble. Only that first 15 seconds after you get it home and put the needle on the record will determine whether you bought a gem, a dud or something in-between. Our members as a whole have a mountain of vinyl gems at home that we would never individually know about, including many that are easy to find and inexpensive. King of the Mountain Vinyl is all about bringing those gems to the attention of our members, so you can add them to your collection.  

September 12th, 2013 - Ki Choi is a formost expert on reel tape machines and their restoration. He owns about 40 machines from Studer, Nagra and others and is the man behind the resoration of many of the machines owned by audiophiles around the country. Ki lives in the Puget Sound area and will take a break from his day job as a nuclear scientist to visit the audio club with a machine and some of his best tapes.  

August 8th, 2013 - Meeting at Mike Lavigne's house to hear his world-class system, including his new Evolution Acoustics speakers and Dartzeel monoblocks. Reel tapes and premium vinyl will be in full effect.

Dogs, burgers, buns, condiments, bottled water, plates and the like will be provided, as well as some newly-styled chicken burgers from our gourmet cooks. Card tables will be set up if you'd like to bring anything to swap or sell. A Vanatoo / Exemplar Audio system will be set up to pump out the tunes. Come ready to socialize.  

June 13th, 2013 - The 2nd Annual PNWAS "Live vs. Recorded" Event  
Featuring Seattle Opera Soprano Kimberly Giordano and Seattle Violin Soloist Marie' Rossano 

After the fantastic success of last year's "Live vs. Recorded" meeting we decided to make this an annual June event for the Audio Society. It's hard to beat the energy and excitement that goes along with a live performance and recording and playing back the performance is our way of putting our own audiophile spin on the evening.

For LvR 2013 we have two musical artists you won't want to miss. We're fortunate to have partnered with the Seattle Opera to find soprano Kimberly Giordano. Kimberly appeared most recently at the Seattle Opera as Suor Osmina in Suor Angelica. She also joined the Seattle Mariners last summer on Safeco Field to perform the National Anthem. In addition, we have Seattle violin soloist Marie' Rossano. Marie has appeared as a soloist with the Seattle Symphony and is also the winner of the 2012 Classical KING FM Young Artist Award. She'll be performing at the Juliard School before our event and with the Salt Lake Symphony after.  

May 9th, 2013 - The PNWAS 9th May meeting will feature a range of turntables from Thorens, a German company that has been in business for 130 years. Thorens was a very popular brand in the early high-end audio days when vinyl ruled. Many of you may remember the popular Thorens TD125 and the TD160 which are still much sought-after today. In 1979, the Thorens Reference Turntable set the high-water mark for reference turntables as much as the Infinity Reference Standard in 1978 set the high-water mark for reference loudspeakers. We'll have three Thorens tables ranging in value from $1k-10k and the club's Rega table as a reference.  

April 11th, 2013 - Don't miss our April meeting when we'll be joined by Emmanuel Go of First Sound Audio (Renton, WA), to demonstrate his fantastic line of handmade tube preamplifiers. Emmanuel is renowned for his attention to detail in his products and he'll discuss some of his philosophies and approaches to design and building. We'll have two Fist Sound models on hand as well as Emmanuel's Berning OTL (output-transformer-less) tube amplifier (and possibly a solid state amplifier), all connected to the club's Genesis 7.2 speakers.  

March 14th, 2013 - We'll be assembling a fantastic system using the club gear with Rene' Jaeger's tube amplifier and Berkley DAC, as well as a Modwright-modified BD-105 player.

February 14th, 2013 - Jim Merod, the Positive Feedback reviewer who raved about our Genesis 7.2F loudspeakers will join us. You may not know Jim is a recording and mastering engineer who's worked with artists such as Tito Puente, Joe Lovano, Tommy Flanagan, Sarah Vaughan, Eddie Palmieri, Wynton Marsalis, Ella Fitzgerald, Stan Getz, Tolu, Los Lobos, Ozomatli, and Luciana Souza. He'll be bringing some of his high-resolution master recordings to demo. 

January 10th, 2013 - We did a meeting about Tweak devices a few years ago and it was great fun listening to a myriad of far out devices and hearing how they affected our sound. This time we'll also throw in a few modified components to up the interest factor. This is going to be a fantastic meeting to get some fantastic ideas for your system at home.

December 13th, 2012 - Join us this Thursday for the Pacific Northwest Audio Society's annual holiday party. Our resident master chef, Jay, will be working up a desert tray and we'll be playing holiday music, so be sure to bring your funniest or most inspiring holiday discs and vinyl. Come be a part of this fun and festive evening.

November 8th, 2012 - One of the most renowned engineers in the digital audio world, Andreas Koch, will join us in November. Through his company, Playback Designs, Andreas has created some of the most fantastic digital audio products out there. He'll have his MPS-5 Reference Player at the club for us to hear. In addition, Andreas will discuss his long career as a designer, starting in the 1980's with Studer Revox and then with Dolby Labs and Sony.

October 11th, 2012 - This month we have a very interesting combination. Our 2012 speaker contest winners and runners up will be bringing in their speakers for us to listen to. We'll play some of the judges selections from the contest. We also have Zsolt Mathe of Z-Infinity demonstrating his tube based preamp and amplifiers. We'll hear the Z-Infinity amps through the club speakers as well as the speaker contest speakers.

September 13th, 2012 - Durand Tonearms will be featured at the Audio Society in September. Come hear amazing vinyl performance from some of the best tonearms out there.

August 9th, 2012 - Vanatoo, Small Size...Big Sound: Join us in August to hear amazing sounds coming from this compact, all-in-one system, designed by two of the club's own members. The Vanatoo Transparent One Powered Speakers include everything you need to make great music with your computer, inside these two 10" high speakers. You won't believe how these little speakers perform...they are awesome. We'll hear the story of the company and its first product as it's on the verge of hitting the market.

July 12th, 2012 - Summer BBQ, Hangout and Swap Extravaganza: Join the group for a summer barbecue. We'll be firing up the grill with burgers and hot dogs. Be sure to bring any albums, CDs or audio gear you'd like to sell or trade, because our Swap Meet will be going strong on Thursday night. For your listening enjoyment we're going to assemble a system with all vintage gear; if you have any killer gear from the good-ole-days that you can add to the mix, let us know.

June 14th, 2012 - "Live" vs. Recorded: Join the Pacific Northwest Audio Society on Thursday, June 14th at 7:30 for a meeting with renowned recording engineer Todd Garfinkle of Ma Recordings for a live recording of budding Seattle woodwind artist Benjamin Zobel. Todd will demonstrate and discuss his unique and innovative recording techniques.

May 10th, 2012 - DSD Demystified! What is this "DSD" creature? Much talk has been generated lately about DSD open-source coding and more labels offering DSD downloads. Most of you know the DSD format from SACD's. Unlike CD's, there wasn't much you could do with the data. This meeting will answer all your questions. Hopefully by the end of the meeting, everyone will be able to download DSD files, set up the computer and enjoy the magic of music in the Megahertz!

April 12th, 2012 - Join us in April to meet Kara Chaffee and see her fabulous line of deHavilland HiFi tube gear. The evening will feature her Model 50A, 45 watt, triode-wired KT88 output stage, mono block amplifiers. She'll pair this with her UltraVerve 3 preamplifier, featuring 100% hand wired point-to-point circuitry, as well as the 6SN7 octal tube, and tube rectification using the 5AW4 / 5U4 rectifier.

To top it all off, Kara will also bring her Model 222 Vacuum Tube Magnetic Tape Playback Preamplifier, which we will pair with a reel-to-reel machine and reels from Bruce Brown's private stock at Puget Sound Studios.

March 8th, 2012 - Many members still remember the magical evening of music we had more than two years ago when Steve McCormack presented his Virtual Reality Engine-1 preamp to the club and pretty much blew everyone away. By the end of the meeting, some members were proposing to spend entire treasury of the club to buy the VRE-1 from Steve! Good thing that cooler heads prevailed...but we still long for that magical moment again.

Here's the chance. Steve is bringing his latest version, the VRE-1C for yet another presentation. This is the first time ever that a remote-controlled version of a preamp sounds better than the manual version using a stepped, discrete-resistor attenuator. Steve will tell us how he managed to do it.

In case you don't know who Steve McCormack is, he was the founder of McCormack Audio (since sold to Conrad Johnson), recorded and engineered some of the most sought after Direct Disc LPs ever made with M&K Real Time, founded the Mod Squad, and invented Tiptoes.

Visitors and guests are always welcome.

February 9th, 2012 - Our February meeting is a very special event which will feature presentations and discussion with two Pacific Northwest audio manufacturers. Coming up from Amboy (Vancouver) WA, Dan Wright, from ModWright Instruments, will be bringing his KWI 200 integrated amp with integral DAC, LS 100 tube linestage (also with DAC), a KWA 150SE SS Power amp (a very special piece - ed), and likely a tube-modified Oppo BDP-95. From Ferndale (Bellingham) WA, Lou Hinkley from Daedalus Audio, will be bringing his Athena speakers. These speakers are characterized by their ability to remain clear as well as natural, with a wide range of music and at all volume levels. In addition, their high (96 db) efficiency makes them amp-friendly, and it doesn't hurt that they're beautiful to look at. Both manufacturers encourage members to bring their favorite demo discs to the meeting. These same manufacturers partnered at the 2011 Rocky Mountain Audio Festival to produce great music for visitors to their rooms.

January 12th, 2012 - The January meeting of the PNWAS will feature an exciting showdown of digital playback systems. This will be both an interesting preview of state-of-the-art digital audio components, as well as a showcase of digital gear our Executive Committee has selected as candidates for consideration in our own digital playback system. Headlining the first half of the meeting will be a duel between the stock Oppo multi-player and a modified player from John Tucker, at Exemplar Audio. The second half of the meeting will pit the stock Oppo against the Eximus DAC. The music will be a mixture of top-notch Redbook and hi-res tracks.

December 8th, 2011 - Annual holiday party and gift exchange.

November 10th, 2011 - Road trip to the Madrona Digital studio, in Bellevue. Be sure to RSVP a few days ahead. Guests, please email / call Darin or Joe to RSVP. You won't want to miss this one.

October 13th, 2011 - The October meeting will feature a comparison of the two very different amplifier topologies. The Class A* Plinius SA-103 will square off with the Class D Genesis GR360. Both of these amps have received critical acclaim in the media and both sound terrific. Special thanks to members Peigen Jiang (Plinius) and Joe Pittman (Genesis) for providing the gear for this event.

September 8th, 2011 - Our next meeting will focus on music, specifically, your favorite music. We are asking that all members and guests bring music that brings you enjoyment, has special meaning, or represents something new that you’ve heard and want to share. We’d like you to bring one or two discs or records, and if you’re comfortable with it, say a few words about what you like about the music. This type of event is always fun and simple, and makes it easy to come up with new additions to your music collection. This event is all about sharing the music you like with the rest of us.

August 27th, 2011 - We will hold our two year DIY project event on Saturday, Aug 27th. Watch our events page for more details as the date approaches.

August 11th, 2011 - Road trip to Mike Levigne's, to listen to his world-class system. Those of you who attended last year and the year before will be amazed when you hear the changes he's made this year. RSVP to

July 14th, 2011 - A few small tube amps will be on hand to explore the allure of high efficiency speakers. We will use the 95dB efficient, Cain & Cain Abby.

June 9th, 2011 - Audio Society member and inventor of the amazing Ground Control tweak, Bud Purvine, will demonstrate his speaker driver modification process, he calls enABLE. This process elimnates the resonance that resides on the surface of the driver, a problem which today's drivers do not address. We'll have two sets of the same speaker (one treated, one not) and you will hear the before and after in an A/B listening test. Get ready to be shocked by the improvement.

May 12th, 2011 - Dan Schmalle (aka Doc Bottlehead) will demonstrate his creations. Dan is renowned in the audiophile world for his low-power amplifiers and headphone amps, which can be purchased as a kit by DIYers. The source will be Dan's reel to reel tapes, from the Tape Project and the gear on hand will include a set of Dan's 300Bs and his 2 watt OTL Set amp, connected to his Straight 8 (eight driver) speakers. In addition, Dan will have four listening stations set up with his headphone amps and several models of headphones.

April 14th, 2011 - Jules Bloomenthal, will give a presentation on the ground breaking work he did with Soundstream Inc, at the dawn of the digital music age. The meeting will include listening to several early digital recordings made by Jules and his colleagues.

March 10th, 2011 - Ted Smith will come by with his new DAC prototype, which utilizes DSD technology.

February 10th, 2011 -  Is Digital Ready for Prime Time?

The club has many members who are dedicated vinyl-philes, and as many members where the CD/Music Server is their primary source. There have been endless debates on digital vs analog - theory and specifications vs "just listen". This month's meeting is not a debate on analog vs digital, but an exploration and discussion on state of the art in analog and digital playback.  

As a basis of discussion, we have attempted to put together a system that is equally optimized for analog and digital. We will be able to compare high-quality analog playback with a pass through an ADC and DAC loop. While this is certainly not exhaustive, it will give attending members food for thought..... and whether with the system assembled, members in the acoustic space of the club meeting can hear the difference between straight analog, and analog digitized and then converted back to analog.

The system will comprise the following: 

Roksan Xerses 20+ record player
Roksan Artemiz arm
MicroMagic Virus cartridge (with ruby cantilever and optimized contour stylus)
Burmester Top Line Ph100 phono stage with built-in 24bit/192hz ADC
Weiss Minerva DAC (plus mods by Gary)
Genesis SMc-1 Preamp
Genesis GR360+ amplifier
Genesis 7.1f loudspeaker

Members are encouraged to bring their LPs to play. 

January 13th, 2011  - Contestants from our speaker contest last August return to show off their creations. From horns to 3-ways to monitors, we will have nearly all of the award winners from the contest.
