Capitol Audio Fest


Did anyone else attend Cap Audiofest this year? I've seen no threads about it, I was only able to attend Friday afternoon but heard some good systems. Favorites for me,  Shindo/Auditorium 23, Zu Audio, Tidal, Classic Audio/Atmasphere, and Deja Vu Audio. I thought the Zu system with Omens and First Watt Sit monos was the best value priced system. Best system overall the stunning Deja Vu vintage system with their field coil speakers just astonishing sound.  I wish I had gotten more time to spend looked like there were lots more rooms this year.

There were a lot of nice sounding rooms at the latest Capital Audiofest.  As in past shows in this location, the smaller hotel rooms tended to sound better than the larger conference rooms.  I am in agreement with a number of postings above.  I too, thought the Deja  Vu vintage room and the MyEmia room were outstanding, the best rooms at the show to me.  

There is so much hype in this forum about Tekton speakers I wanted to hear them.  I came away impressed with how good they sound relative to the price quoted on them.  The only commercial shortcoming would be the size of the system.

Volti had their best room at this show.  I was not that impressed with their setups in the past, probably because the room and accompanying electronics did not show them at their best, but, this year, with a physically smaller system, their room sounded quite nice (warm and harmonically dense, without sounding mushy).

The Shindo/Auditorium room was pretty good sounding.  I am familiar with WE 755 single driver systems which tend to be very clear, dynamic and exciting sounding, but, they also tend to be peaky, thin in bass/midbass, and extremely colored.  The Auditorium speakers did a decent job of taming these negative tendencies with only a modest loss in dynamics and immediacy of the Western Electric originals.  But, they only rated, to me, number three in the single driver category at this show.  I  was really surprised by how good the Charney single driver system sounded (Voxactiv driver) and it delivered the goods dressed in a reasonably nice looking and compact cabinet.  I heard decent bass and sound that did not become strained at fairly high volume and I did not hear as prominent an upper midrange/treble peak as I've heard with most single driver systems (surprisingly, I thought it was a bit too soft in the upper range).  The other system that impressed me was the Rethm Bhaava; it was not as well rounded as the Charney, but, it was about a third of the price.  

The German Physics omnidirectional speakers sounded pretty good, they managed to deliver the expansive soundstage you expect from such speakers while having a bit more solid and grounded center image than I've heard with other similar designs.  The bass sounded well integrated and balanced.

I am not a fan of most modern dynamic speakers featuring space age cabinets and exotic material drivers.  Most sound harmonically bleached, brittle, and, while they can deliver high volume levels and sound "fast,"
they tend to be lifeless sounding at modest volume levels.  That was not the case with the YG  Carmel 2's I heard at this show.  While not being quite as warm as I like my speakers, they sounded very good otherwise.

One of the bigger rooms, running a  Channel D music server also sounded very good.  If I recall correctly, the speakers were Vandersteens.

The Deja-Vu room with "non-vintage" and more modestly priced gear sounded very good for the money.  The system is modern, but old school (hence non-vintage), with tube electronics.  The new Harbeth 30.2s were in the system.  It is hard to tell under show conditions, but, compared to what I've heard of the 30.1s, these sounded better: a touch less obvious that the speakers are boxes, and the slightly annoying sibilant peak in the upper midrange was not evident (I like the 30.1s; I like the 30.2s a little bit more).
jond,

The Channel D room was a touch bright, but, I took into account the nature of that kind of reverberant space.  I think you would have really  liked the Charney and Rethm speakers.  Neither were bright and they were also, like the Auditorium, not cursed with a prominent peak in the upper midrange.  Did you get to hear the Volti speakers?  This is, for a horn-type system, a reasonably compact system that delivered good sound.

I also should have mentioned the Burwell and Sons horn system.  I thought they sounded quite good too.  They were warm sounding and delivered the saturated harmonics that I like from old school systems (tube electronics, pleated paper surround woofers, compression drivers, etc.).  They were also surprisingly compact and nice looking; I thought they were monsters from the pictures I have seen.  But, at its price point, Deja Vu can build a custom system that is precisely what you want (and hopefully can afford).

I should also give favorable mention to the DC area DIY group and their room.  This time, they only displayed one setup instead of rotating several systems so they were not as ambitious as in prior years.  But, the system was quite nice sounding.  It was essentially a cube without a top and a back (open baffle design).  An 18" woofer fired downward and the front baffle held a coaxial midrange/tweeter.  The box was made rigid by using round dowels across the open top and open back (great idea for reducing interference with the back wave of both the woofer and coaxial drivers).  The speaker looked to be quite easy to build and the parts were quite inexpensive.  This makes it a classic DIY product--clever design substituting for expensive parts and construction.

When I heard the Burwells, they were being played at low volume and sounded not at all piercing.  But, it might well be the case that they would behave poorly at higher volume levels.  That actually is an issue with horn systems, particularly when they are not really large in size.  As volume goes up, horns tend to become "shouty."  I did not get a second crack at hearing them so I may have missed the bad behavior. 

I heard the GIANT Von Schweikert speaker/VAC room a couple of times.  One audition was horrible sounding--very bright and brittle sounding, but, on another occasion, it was pretty decent (though hardly my choice for a system well north of half a million dollars).  The better sounding demonstration was at a much lower volume than the one I could not stand, so it might simply be a matter of inappropriate volume.  I get the feeling that the people running demonstrations think that volume levels have to be extremely high to impress the public; I am more impressed with systems that deliver great sound at low volume.

As for the Classic Audio/Atmasphere room, it was bright sounding and also brittle sounding for my taste.  In other years, it has sounded better, but, the brightness has always been a part of the sound. 

Another room that I liked that I forgot to mention was the Conrad Johnson room with the "cheaper" model of Tidal speakers. 

Charles1dad,

Yes, I think the Classic Audio speakers are bright and mid-bass is thinner than my ideal.  OTL amps, like the Atmasphere amps, and field coil speakers, have as their primary area of superiority, incredibly lively sound--very fast and dynamic and immediate sound.  But, pushed too far, this sound can be edgy and brittle; it is a matter of taste.  By contrast, the stacked Quads in the Emia room and the field coil system in the Deja Vu room were also quite dynamic and immediate sounding (though not as extremely so), but the initial attack of musical instruments sounded more natural to me on those systems so that the sound was smoother and more natural while not being muddy and slow sounding.  It is a matter of tradeoffs and priorities. 

The Zu speakers also have a very dynamic and immediate sound.  As most shows, they are matched to high powered amps to emphasize this strength by being played at high volume levels (it is startling to hear, but also tiring).  They really can be made to sound much more refined and relaxed, but, I suppose, at shows, the idea is to grab attention. 

I went to Deja Vu this weekend and heard the big horn system that they brought to the show in a bigger and better-suited room.  In this setup it sounded substantially better than it did at the show.  I noticed that it does not sound quite as good when the system is turned on than when it has warmed up a bit; apparently, the field coil drivers and/or the tungar power supply need to warm up a bit before the system sounds it's best (bass is boomy and ill-defined until the system warms up). 

I was particularly struck by how good the 597 tweeter sounds--the system was very airy and open sounding without even a hit of harshness; this was the smoothest top end I've heard and it was so well integrated it was like there was no tweeter present, but, the sound was not lacking in high frequencies.  The 555 midrange had the smoothness I would expect from this driver, but, the G.I.P. replicas also delivered the kind of detail that made it sound more like a Western Electric 713B driver than other 555's I've heard (a VERY good thing).  

The bass on the system is not quite what I would find ideal, but, this is always the case until the system is specifically tuned to a particular room, system and personal taste.  

Sal,

I really liked the system with the Goodman woofers and the YL 5500 compression drivers too.  It might have been a little bit more dynamic sounding and vivid than the G.I.P. system, but, as with almost everything audio, there are some tradeoffs.  To me, the YL/Goodman system was not quite as smooth and coherent, particularly with respect to the treble response, and I heard a bit more coloration, particularly in the form of tonal unevenness with solo piano.  But, both are great, and I have not heard anything that sounds bad with YL drivers.  The YL horn tweeters are also very good.  The big plus with the non-fieldcoil system is not having to deal with a power supply and warm up issues.  From a commercial point of view, the plus with G.I.P. drivers is that they are currently being manufactured while the YL stuff is vintage and quite difficult to find which makes production of such systems extremely limited.
