It was a big Leap.
I think half, or it just seemed like it, of the club’s membership squeezed into Russ Katz’s townhouse—home of The Vinyl Revivers. Russ has been a corporate member of the DC Hi-Fi Group from the beginning and is a big supporter of the club. Hosting a club meeting takes a lot of work and Russ has done many. Be sure to thank Russ and Roslyn at the next gathering. It was a beautiful day, a little chilly, but anything above freezing in February around here is a blessing.
The meet followed the usual format. Meet, greet, drink, eat. Really good sandwiches with all the accouterments that a polished host provides.
Chris filled us in on the latest pertinent news including a discussion about the ramifications of the Apollo Masters fire. This was one of only two manufacturing plants that make lacquer masters for the vinyl production industry.
For the DIY’ers in the club, Chris let us know about a great suggestion for a new affordable high-end 2 x 40 W Class D audio amplifier HAT board that attaches onto a Raspberry Pi Zero. This creates a solution ideally suited for DIY audio projects. Link to the article is here
Chris recently told us about one of his new speakers (Magnepan LRS) that has received great reviews. I have heard them twice at audio shows and I agree with the reviewers and Chris that this speaker performs way above its price point. Chris has found a simple mod to push this speaker’s transparency even further by replacing the factory stands with Magna Risers.
For the guitar enthusiasts in the group, there is going to be an open house and concert at PRS Guitars in May.
And Qualcomm is pushing the Bluetooth protocol further in speed and audio quality with new chips.
In Russ’s basement showroom he had Sonner Legato Duo’s that are just plain fine. These are 2.5-way bass ported enclosure with a reasonably high sensitivity of 90db and a freq range of 37Hz to 23kHz. I wish I could have spent some quality time with them. I have only heard the smaller monitor styles at the audio shows and loved them. Bryce Allen from Rega was showing off the Rega Planar 8.
In the first floor sound room, we had the ATC SCM 19 bookshelf speakers on stands demoing the Geer-Fab D.Box SACD Player-to-DAC HDMI/DOP interface. This magic box can extract DSD64 and PCM 24/192k from the HDMI data of a player/transport with HDMI output. Don’t give your SACD’s away just yet! Since Oppo stopped making their universal player, this is one of the only ways to get Audiophile SACD sound these days. The system also included the Gold Note DS-10 DAC/Preamp/Streamer. The DS-10 is the latest generation of DAC using the brand new AKM AK4493 chip with PCM resolution up to 768kHz/32-bit and DSD up to DSD512. In addition to converting the audio signal, it is also capable of sending it directly to a power amplifier. This makes it very versatile analog line preamp. It is also the latest generation streamer with a high-performance headphone amp that features two sensitivity levels to drive any type of headphone. The muscle behind this high tech front end is the Goldnote IS-1000 integrated and streamer box. This is a 125 watts/ch box. Way cool.
Amar Krajvansh of Aurorus Audio Headphones set up a listening station with his Borealis open-backed headphones. These are in production now and he has been selling them as fast as he can make them. They are really sweet, detailed and refined. A completely mature product after a couple of years in research and development.
This was a very full agenda and a ton of information was exchanged. We had just a few raffle items and the winners were pleased.
Again many thanks to Russ and especially Roslyn for opening up their home to our invasion.
With the threat of bad weather, we still had a good group of members making the trek to Alexandria for another very pleasant get together at Greg Viggianno’s condo party room. This was a combo meeting with DC Hi-Fi Group and the Carver enthusiast club. They are a worldwide owners of Carver vintage products. They have a forum called “The Carver Site”.
The meeting followed with the usual format of “meet and greet” with pizza and various liquid refreshments. After way too much pizza, we had a short business meeting and quickly delved into a listening session with some interesting equipment. John brought his digital rig consisting of his MacBook and the superb Mytek Brooklyn DAC. Completing the front end was John’s Rogue RP-7. John brought two speaker systems—a stand mounted monitor from Studio Electric M4 and the new Martin Logan Motion 20i. The 20i is a compact floor stander with an Air Motion folded ribbon tweeter. This type of tweeter is becoming very popular now that the AMT Heil patent has expired. Below the tweeter are a pair of 5 ½ inch aluminum cone woofers. Claimed frequency response is 46Hz to 25kHz.
The power amps for this set up was a real Yin-Yang affair. First was from the Carver Group, a vintage Caver M500t that was highly modified for higher power (400 watts), lower distortion and tighter control.
Next up was the McGary SA-2. This amp is a modern take on the classic 6550 family push-pull amp. The Amp is self-biased so one can roll in any of the KT-XX’s for the KT66 the KT120 with no problem. Mike McGary builds the amps himself in Virginia. Point-to point wiring is used along with the best possible components.
The Amp has a bunch of features such as adjustable feedback (1 to 9db’s), balanced or unbalanced inputs, switchable (on the fly) between Triode and Pentode modes and the ability to strap this amp to mono so one could have dual monoblocs.
Mike presented the members with a brief description of the amp and his plans to include in the future a full function modular preamp.
The raffle winners received some goodies and we all went home smiling
See you next month!
I have just about three or four more rooms I wanted to highlight.
One of the most highly acclaimed rooms at the show was the GT Audio Works room just off the Atrium. I have to agree. Greg Tekesh’s hybrid planars have always presented a slamming sound. Not just excitement, but a highly musical experience. Specially designed open baffle servo controlled subs easily keep up with the planars quickness. The open-baffle sub-woofers operate from 15Hz-65Hz and include a user adjustable electronic crossover built into the provided amplifier. The open baffle subs are designed to blend seamlessly with the dipole planars. They are configurable for 2 -6 12″ sub-modules per channel. This allows for consistent results in rooms from small to large with a system that has a frequency range of 15Hz to 30kHz. Pass Labs provided the power and control.
The electronics were housed in a beautiful custom made cabinet made by Bruce Schuettinger (DC Hi-Fi Group member) of Mozart Audio Furniture. A three bay cabinet with a Spalted Maple veneer finish was shown. All interior shelves are isolated and and decoupled from the frame including the top which is literally floating. The feet are Stillpoints for maximum isolation from room vibrations. This is one amazing looking cabinet.
The VAC/Von Schweikert room always impresses for the sheer magnitude of the presentation. It is a rare sight to see this much equipment for one system. For most of the weekend they were playing the big VS Ultra 11 statement speaker. I have heard this set up numerous times and its a big sound. Extreme Hi-Fi. If you are into this kind of system then this is the best at it. On Sunday, it was a very different story. They were playing the much smaller VS Endeavor SE. I was blown away. All the same electronics and we have that same room filling sound but much more natural and musical. Totally involving instead of bowling you over. No sledge hammer here. I have always liked the VAC sound, I am a tube guy after all, but this was the best I have heard in a big system.
I have never heard Tekton speakers sound as good as they did in room 402. The new MOAB is their flagship speaker with fifteen high frequency drives in an MTM array and two 12 inch woofers. The specifications are 98dB 2.83V@1m sensitivity and a 20Hz-30kHz frequency response. But of course, I have never heard the Tekton being pushed by the incredible McGary SA-2. I really enjoyed listening to these behemoth speakers. They were coherent, precise, and smooth. I give the nod to the McGary amp for carrying the musical load here. Every room that has the McGary SA-2 fills my need for emotional involvement with the music. So the common denominator is the SA-2
Jeff Joseph of Joseph Audio never disappoints and surprised me with a unique sound that just makes me happy. He was showing the Perspective 2 Graphene diminutive floor standard that pumps bass far more than its specs say. Just 36 inches tall and 8.5 inches wide this baby can pressurize a room like 10 foot tall monster. This was easily a system I could live with which included Bel Canto electronics and Audience cables tying it all together.
One of the true magicians of our industry is Peter Ledermann of Soundsmith. I say this because his products are transformative. The music in Peter’s rooms always force me to sit down, close my eyes and listen. I hear the music. Then I open my eyes and I am overwhelmed by the minimalism of the room’s equipment. Just a pair of small stand mounted monitors, a turntable, preamp and amp. That is it. But the sound is of some massive kit of stuff. This time we were hearing the Monarch Bookshelf (just 14 inches high on 3 foot stands), the Strain-Gauge cartridge, the Signature Series, dedicated Preamp and the HE-150 MOSFET Power Amplifier (200 watts/ch). Peter had two turntables set up and he would alternate between the Strain-Gauge and the Hyperion cartridges. Both sound wonderful but the Strain-Gauge is very different sounding cartridge and is one that I am beginning to like very much. Soundsmith‘s room is one I always seek out and make sure I have time to enjoy the music.
At most audio shows I have been to its usually a very small number that are actually musical to my ears. With CAF this year, there were more than half that sounded good to me and there were about twenty that were exceptional. I hope that this trend continues at the Florida Audio Expo and Axpona next year.
What most readers seem to want is a declaration of a “Best in Show”. I have reflected on this for quite awhile and decided not to copy other writers in this genre. This hobby is really a journey of one of two things. Either we are in a competition to have the “Best” or we are on a mission to get the most emotion from our love of music. Both of these are viable as long as it keeps the manufacturers continuously improving their products. I am finding that the digital side is very good now with musicality at a very high level. It is always going to sound different from analog but I am finding digital can be very satisfying. It’s really about the music and what the music does to us.
What Gary Gill continues to bestow on us are live music presentations. If you are on the journey of musicality then you must hear the live music. It was obvious that all these presentations were from musicians that love what they are doing. It came through to my heart and soul. I give my “Best in Show” to all three groups.
Jay Summerour & Friends treated us to some juicy Piedmont blues. These guys are well know in the DC area playing for many Smithsonian events. Their latest recording is “The Best of A Little Bit of Blues”. I’ve ordered the CD!
Embassy Jazz Messengers. This group has played CAF for a couple of years now and they put forth a great straight ahead jazz set the everyone within earshot seem to enjoy in the hotel bar Saturday Night.
The Spellcasters played music from the Anacostia Delta in the Washington Theater. This group transported me. Music I have never heard before. Bluesy, Jazzy, free wheeling music that just about evoked every genre of music except Gregorian Chant (maybe). I felt very lucky to have been one of the eighty or so in the audience.
Capital Audiofest has grown to be a major show now and we are very lucky to have Gary Gill and his crew of volunteers to put on this show each year. This is a major effort and work has are ready started for next year. I can’t wait to see what’s in store for November 2020. See you there!
Gramophone, Gaithersburg, graciously hosted our December meeting and Christmas party. Chris Murphy, who has moved down from Overture in Wilmington, DE., has taken over the Gaithersburg Design Center and become the Regional Business developer. Chris has been a great friend and supporter of DC Hi-Fi Group and welcomed us with open arms and shared the Gaithersburg store on a Sunday afternoon for great greets and eats.
Gramophone had the new Totem Metal small floor stander on demo with McIntosh electronics. These highly efficient (91db) surprisingly pumped the low bass (26Hz – 22kHz) and had no trouble presenting a detailed and wide image. A lot of music from such a small floor stander (11 in wide, 43 in tall). I learned that there were no crossover parts in the woofer circuit and only a single cap in the tweeter circuit. Keeping it simple translates into keeping it clean and precise.
We were some of the first to publicly hear the brand new Lyngdorf MP-60 Pre-Processor for AV. Gramophone has a great HT room where the MP-60 was controlling the AV with ease. This unit is been available for a few weeks and was premiering at Gramophone.
We enjoyed a convivial atmosphere with plenty of the usual libations on hand to loosen tongues.
Yes we sort of had a meeting but soon it was time to EAT!!! Good stuff…Yippee ki-yay!!!
And of course, even though we are all winners, a few got this reaffirmed by getting their raffle tickets pulled and went home with some goodies supplied by Gramophone and DC Hi-Fi Group.
Again we all need to give a big hug to Gramophone and John Gatski for putting this all together.
If you did not take part in this “best ever” CAF you missed a great show. Everything and I mean everything, except the Hotel’s cafe menu, was just grand. More rooms than ever. The show has grown to the point one can not spend quality time in every room in the short three days. It forces you to pick and choose equipment that you really want to experience. The other thing is for me, there were more rooms that sounded musical than ever before. Much less than the usual upfront, bright sound that some consider the “Modern way”. There was a good balance between digital and analog sources, both sounding good to these old and crusty ears of mine. The Marketplace was full of new and used vinyl, and accessories for your perusal.
There is a big “BUT” coming……
But what stood out above everything else (for me) was the live music that Gary Gill provided for the lucky few that took advantage of the three presentations.
Now for the listening rooms. There will be no attempt to cover it all. Not even close. So this will be the highlights of the highlights.
I found most of the rooms sounded very good. The usual standouts were there. Doug White’s, The Voice That Is, in the Wilson Room, always puts on a room that has it all, yes expensive stuff but this is one room that is always very musical.
Lou Hinkley, of Daedalus Audio, had a grand display in the Randolph Room. Lots of big sound and music, that I could have spent hours listening too if I did not have a job to do. But his room up on the 5th floor was a sleeper. On my short list for best in show. The Muse Studio speaker with BorderPatrol electronics, and Triode Wire Lab interconnects, power, and speaker wires, the music was sublime.
When I was walking down the back hall and saw the Jeff Fox (Command Performance AV) was in one of the Plaza ballrooms, I thought to myself that this is going to be a disappointment. Not for the equipment but because of the room. These cavernous rooms are just impossible to make sound good.
Jeff was showing John Devor’s beautiful Orangutan Reference , these are the ultimate Devor speaker. They were driven by the new Luxman MQ-300 power amp. Somehow Jeff and John after what was explained with me many hours and different geometries were able to get a most involving sound.
I heard the big Kef Muon’s last year in the VPI Jefferson room. I was not impressed. But this year the Mark ll in the Adams room was a completely new story. I heard music, not Hi-Fi. Was it the new mods to the speaker. Was it the room or was it the new Krell Amps. Surprise, surprise. There were Krell amps in other rooms and they sounded good too. Krell is making musical amps!!!
What’s great about these exhibitions is you get to see and hear equipment you would never experience anywhere. One such product in room 523 is the MC Audiotech Forty-10 from just outside of Philly. This is a full range two-way system with an unusual cloth covered curve array consisting of 100 in house designed drivers covering 100Hz to 20kHz sitting on a bass unit which they call a folded cube. I believe it is two 18 woofers firing in to a chamber that is ported out the back. Each woofers back wave is ported out its respected grill on the front. This design provides a very efficient way to plumb the depths to 20 Hz. Efficiency is stated as 93-96 db at 1 meter. The sound was very full of life. I liked it.
Also up on the 5th floor was the Salk/McGary room. Jim Salk of Salk Sound has brought his beautiful speakers to almost every CAF. He was at the first CAF in 2010 where I met Jim and heard his speakers for the first time. I was taken aback first by the exquisite craftsmanship of his woodworking. I am a bit of a woodworker myself and I know how difficult it is to finish a product to the level that Jim does. Then there is the sound. Salk has always presented a wide, deep and musical image. For the past two years Jim has been exhibiting with Mike McGary’s amps. Mike has been hand building these amps in Virginia. Mike was showing his new SA-2 KT88 P-P 80 watts/channel. These are classic push-pull amps with some innovative takes on biasing and powering the output tubes. Whatever Mike does the results is most musical with detail and speed to keep young ears happy.
I have met David Janzen or Janzen Electrostatic Loudspeakers many times at previous audio shows and once at a special presentation to the DC Hi-Fi Group of his speaker. I have recently gotten involved with electrostatics in rebuilding a few pair of Quad ESL (57’s). I like them so much I kept a set for myself. There is something about the speed and transparency that just draws me into the music. It’s just more interesting. David was showing his latest version of the Valentina Active. This an active speaker with dual 500w Hypex NCore amps biamping the woofers and electrostatic panels.There are both digital and analog inputs.
Linear Tube Audio amps and preamps were all over the show, and LTA supplied the micoZOTL preamplifier. You could really hear what this preamp doesn’t do to the music with the very accurate Valentina Active. David said it took much effort to get a balanced sound in the difficult hotel room. He settled on a placement along the long wall which put the listener in almost a near field placement which was fine for me. (A handful of vendors chose to exhibit this way and those rooms all sound very good) The sound sucked you into the music. It was rich, full, life like, and rewarding.
The winning room for me was the Sonners/Rogers Room 558. The Sonner Audio Allegro Unums are just amazing speakers that play throw and image far bigger that any room I have ever heard them in. I always have to look twice to make sure I am seeing/hearing what I am actually seeing/hearing. Just blows my mind. The amplification was from Rogers High Fidelity PA-2 phono stage and KWM 88 Corona integrated. Front end was either the Mytek Manhattan ll DAC or the Dr Feikert Volare TT
Volti Audio, BorderPatrol, and Triode Wire Labs have been exhibiting together for a number of years and each year at whatever show always get very high praise. This year they managed two rooms. Room 316 with Volti top of the line Vittora system is a fully 3 way horn loaded system including an ELF (Extended Low Frequency) cabinet. I do not think the ELF is needed in these bass heavy hotel rooms, but Greg let me know the low frequency push is fully adjustable. The music was so involving. One just wanted to sit and toe tap the day away. Volti’s tagline is “Just Have Fun” and that is just what his speakers make you want to do. The rest of the equation for this pure musical experience is the BorderPatrol electronics. This represents over 30 years of exploration into what makes a electronic circuit get out of the way of the music. Gary Dews will not make changes for change sake and just keeps producing musical amps, preamps and DAC’s. If there was ever a question whether one should go with either digital or analog front end the the answer is is found in this system. And speaking of this the system, a big part, is the cabling. The synergy one gets with a complete cabling from one company for the whole system is quite obvious. Pete Grzybowski of Triode Wire Labs takes great pride in hand constructing every one of the cables he sells. They are made some of the best wire stock every made. These are most likely the best sounding cables at any price, but sell for a very reasonable amount. These cables are the best value out there. The same can be said about the system in room 309. Just about the only differences were the Volti Audio Rival speaker. This speaker is about one third the cost of the Vittora but can rock out pure music like its big brother. Greg was also showing in static display the new special edition version with curved sides to improve internal resonances.
Dennis Clark of The Leesburg Listening Room had two rooms. I only spent time in 238 the Krell/Altra Audio room. Alta Audio loudspeakers is another high value product in my book. The Alex is in the middle of the line and in the sweet spot for bang for the buck. Here also was the surprisingly good sounding Krell electronics that included Krell Duo 300 XD power amp and the Illusion ll preamp. The analog front end was the VPI 40th Anniversary TT and Voyager phono preamp.
One of our DC Hi-Fi Group members, Amar from Aurorus Audio told me the headphones had been under serious development for about two years. There are two versions—a closed back called the Australis and the open back is called the Borealis. Amar had been reviewing headphones and giving feedback to local DIYers for several years before finally joining with Aurorus to help with tuning and development. The units use a 50mm 32ohm dynamic driver that Amar told me was identical to the driver used in the Kennerton Vali. Amar was using the LTA MZ2 headphone amp. The sound was glorious for the closedback version. There was too much ambient noise to be able to make a judgment on the open back, but since the same driver is being used I am sure they would sound as good. His web site will be up soon but here is a review from Den-fi. Also, Stereophile writer Herb Reichert enjoyed the headphones as well.
That is all for now. I have about ten more rooms I would like to highlight soon.
