Mark Henninger visits the Washington DC area's largest annual audio show to sample the latest high-end 2-channel gear as well as some vintage systems.
High-end audio shows are a fun way to spend a day. Such shows offer an excellent opportunity to sample some of the most expensive and esoteric stereo systems out there, many more than you'll find at a typical audio dealer's showroom. Yesterday, I woke up at 5:00 AM and hitched a ride from Philly to DC with AVS member jwhip (Joe Whip). We arrived just before the show started and met up with Allan Stock, a friend of Joe's, and we resolved to visit every room at the show before the day concluded.
The Sheraton in Silver Spring, where the Capital Audiofest took place.
As soon as the doors opened, we hit the demo rooms as a group. The Capital Audio Fest isn't too large for a one-day visit—as long as you bail on the rooms that don't grab your attention right away. Since it was Friday morning as opposed to a Saturday, it wasn't too busy, so we found it was easy to get prime seats in each room we visited. Here's what I saw and heard, starting with the larger ballrooms at the Sheraton hotel in Silver Springs, MD:
The Linden Room
The first room of the day married a Bricasti M1 DAC and a pair of Bricasti M28 mono amps with a pair of Tidal Audio Piano Speakers from Germany. The source was a Windows laptop feeding the M1 DAC via USB, a setup that was very popular at the show, which I was glad to see.
Bricasti Design components and Tidal speakers sound great together in this system.
The overall sound was smooth and eminently listenable. When I thought about what the sound reminded me of, I came up with butter and silk. Instruments rendered faithful to scale, and although I did not experience goose bumps, I found it quite easy to enjoy the overall sound. We listened to a bit of Tchaikovsky that was from a raw track, an unprocessed DSD 64 recording in a symphony hall. It definitely sounded like a faithful reproduction. Other demo tracks included Toni Braxton singing "Unbreak My Heart" as well as "The Town Burns" by John Williams. My main complaint is that the soundstage didn't have that much depth to it, regardless of which track was playing. Overall, though, it was a nice start to the show.

The Cedar Room
This room featured reel-to-reel source material playing on a United Home Audio tape deck reproduced through MBL 116F Radialstrahler speakers, which feature novel omnidirectional mid- and high-frequency drivers incorporated into a 4-way design. Power for the inefficient MBLs (83 dB) came from four Jolida Luxor series monoblock tube amplifiers.

The demo featured the track "Duo for Violin and Cello" from the album Duo Virtuoso by Elaris Duo. The reel-to-reel recording sounded great, but not tangibly better than well-mastered digital tracks I have heard. Even so, it was cool to hear top-notch tape-based analog audio. It was a very expensive rig for a very particular sort of well-heeled audiophile with a taste for novelty. My main complaint was the lack of goose bumps, which to me is the best sign of exposure to rarified audio fidelity.

I don't know if they help the system sound better, but these tubes are gorgeous.
The Hickory Room
This was the first "uh-oh" moment of the show. I usually enjoy the sound of innovative horn-loaded speakers, and the Sadurni Acoustics Staccato horn speakers sure fit the bill—they looked a bit like jet engines. They are a 4-way design with 110 dB efficiency, and I figured they would make for a fun demo. However, as I started taking pictures I noticed loose wires near the topmost tweeters—they were not connected to anything! When I pointed this out to Joe and Allan, they asked about it—apparently, the tweeters blew up earlier that morning. Given that revelation, we decided not to stay in that room because we did not want to demo malfunctioning speakers, even though other attendees were doing just that.
I happened to notice that this tweeter was not connected.

The Persimmon Room
My first thought upon entering the Surreal Sound/Live Sound Designs room was "welcome to the wonderful world of speakers based on a single full-range dynamic driver." The Surreal Speaker includes one full-range driver plus six 10-inch bass drivers. Power for the full-range driver came from a 30-watt-per-channel (into 8 ohms) Atma-Sphere S-30 tube amp, featuring a frequency response of 1 Hz - 200 kHz within 3 dB. The bass drivers got their power from a Crown XTi-4002, a stereo amplifier that outputs 650 watts/channel into 8 ohms and 1200 watts/channel into 4 ohms. I use a Crown XTi-2002 to power my subs at home, so it made me smile to see an amp from the same series used in a high-end rig.
The Surreal Speaker has a rather unusual design, in this image you can clearly see the bass drivers.
Atma-Sphere's S-30 tube amp is a cool-looking piece of gear.
The system was a bit bright—as always that could be an attributed with the source, the room, or the content—but it had quite good resolution overall. I did not hear it strain or distort while playing "Cotton Tail" by the Duke Ellington Quartet from the album Duke's Big Four. There was an aura of immediacy to the system reminiscent of electrostatic and planar-magnetic speakers. Imaging was precise. While it's not a system I would pay for, I wouldn't mind listening to it a bit more.
I smiled when I saw a Crown XTi-series amp taking care of bass duties.
The Willow Room
In Classic Audio Loudspeaker's demo room, there was no avoiding the presence of the $32,000/pair T-3.4, a reproduction of JBL's legendary Hartfield speaker system. They are huge, gorgeous horn-loaded speakers. Sadly, they were positioned too far apart in the relatively long and narrow Willow room.
This JBL Hartfield reproduction, the Classic Audio T-3.4, is one serious-looking loudspeaker.
I listened to a dynamic, full-range reproduction of Willie Nelson and Sinead O'Connor singing "Don't Give Up"; overall, it sounded natural except for the lack of proper stereo imaging that was the result of the unusual room layout. It's a system I'd like to revisit with some of my own music, under more ideal conditions. That goes for the other speakers in Classic Audio's repertoire, including the also-gorgeous T-1.4 Reference. All of Classic Audio Loudspeakers' drivers use field-coil electromagnets that take the place of the permanent magnet found in most drivers. Power for the T-3.4 came from a pair of Atma-Sphere Novacron tube amps, 60-watt monoblocks with a frequency response of 1 Hz - 200 kHz within 0.5 dB.

The Walnut Room
This was a no-holds-barred attempt at best-in-show sound by Philadelphia-based high-end audio dealer The Voice That Is. The center of attention was a pair of Tidal Audio Agoria loudspeakers, which go for about $100,000/pair. The rest of the audio chain included a Bricasti M1 DAC, an Aurender Reference music server, and a Tidal Audio Impulse amplifier that costs $32 grand and outputs 190 watts/channel into an 8-ohm load, 360 watts/channel into 4 ohms, and 680 watts/channel into 2 ohms.

During the demo, I heard "Brand New '64 Dodge" by folk singer Greg Brown off the album The Poet Game. It's a rich-sounding recording that shows off the potential of the system, although I found the track also flattered my own system when I got home. Nevertheless, it was a great-sounding stereo—as well it should be, given its $150,000+ retail value. In addition, I've started to wonder if large plastic trees help a hotel room's acoustics. Could it really be mere coincidence that such trees surrounded one of the best-sounding systems? Well, the room also included sound-absorption panels described as WAF-friendly, since they included custom photographic printing, making them look like hanging art or photo enlargements. Perhaps the combination of panels and trees did the trick.
These acoustical panels feature custom printing, which reportedly increases the WAF factor.
Do plastic trees help stereo systems sound good in hotel rooms?
The Magnolia Ballroom
The next stop was the show's pop-up music shop with the requisite crates full of records. I also saw Mark Waldrep from AIX records, who was there as a vendor with his collection of exquisitely recorded high-resolution and multichannel audio offerings on Blu-ray, DVD-Audio, and via download. Mark had a listening station with dual Oppo PM-1 planar-magnetic headphones, which made his recordings shine. It was my first time listening to the Oppo cans, and I am very enamored of the sound as well as the fit and finish.

The Elm Room
This was my first exposure to Zu Audio and the Utah-based company's Definition loudspeaker, which runs $12,750/pair. The setup included a Rega RP-6 turntable and a nifty-looking Rupert Neve Design 5060 mixer. Power for the high-efficiency Definitions came from a pair of First Watt Sit 1 monoblock amps, a 200-watt class-A design.
This was the only room with a proper DJ setup.
I found the Zus to be precise and analytic speakers, not unlike studio monitors, as I listened to the Woodie Guthrie-penned track "Careless Reckless Love," performed by Jay Farrar and Jim James on their album New Multitudes. Twin guitars, harmonica, and vocals kept it simple and showed off the amount of detail the Zu Definitions could render. I only had one complaint—the sweet spot was very narrow, and the soundstage collapsed completely when I was just slightly off center. The Zu Definitions are speakers that work well for critical listening by one perfectly situated individual. I can respect that.

The Hawthorn Room
The main attraction in the Hawthorn room was, fittingly, the Hawthorne Rainier MKII open-baffle speaker system. The Rainier MKII is a true full-range speaker that uses an air motion transformer-style tweeter. The system featured Dirac Live room correction running on a Core Audio Technology Kryptos S1 Windows-based music server. A Datasat RS20i preamp/processor took care of active crossover duties, while Core Audio Technology Kratos fully digital amplifiers provided power. The Kratos is an interesting amp because it is all-digital, so the system itself does not utilize conventional DACs. Instead, the amplifier directly amplifies the bitstream input and converts it to analog for output to the speakers.

From a design standpoint, this was one of systems of greatest interest to me; open-baffle speakers, active equalization, and digital amplification are approaches that I typically associate with audio transparency. In practice, the system was almost piercing in its sharpness. The treble reminded me of the short time I had a pair of Grado SR325 headphones—the treble was so sharp, it made me think of glass shards as I listenend to "No Sanctuary Here" by Chris Jones from The Stockfisch DMM-CD/SACD. Perhaps it was the recording that was overly bright, or the room EQ was a bit off—all I know is that I wanted to like the system more than I actually did.

I'd like to hear the Hawthorne Rainier MKIIs again; something was off in the presentation at that show. It's the sort of system that will keep the turntable-and-tubes crowd on their side of the fence.
The Maple Room
I love an ear-opening experience, and that's what I got with the system put together by Daedalus Audio. Elvis sounded as good I've ever heard, as if it was a modern recording, thanks to the system's excellent rendition of "Fever" from Elvis is Back.
Each Daedalus Ulysses v.2 speaker looks like a pair of 1970s-era 3-ways stacked with the top one upside-down. It sounded great to me.
Check out the unusual driver arrangement on the Daedalus Ulysses v.2s.
As an aside, I spotted the somewhat silly-looking Modwright modified Oppo BDP-105, which had a pair of vacuum tubes sticking out the top. I'm not sold on the benefit of tubes over solid state, so to me it's just silly to see a great-performing player like the Oppo modified in that manner. However, considering how popular Oppo players are, I'm guessing that the tube crowd didn't want to feel left out. I'm not sure if tubes justify the $2500 modification fee; on the other hand, it's hardly the craziest or most expensive tweak I saw at the show.
What the heck is this blasphemy?
