Atlanta Audio Society

July 15, 2001 Program of the Atlanta Audio Society

The Sunday, July 15, 2001 Program of the Atlanta Audio Society was held at the Dunwoody North Driving Club and Tennis Clubhouse. It was co-hosted by the Audio Society and SoundsRight Audio (Mike Masztal, Roswell, GA) and featured the Avantgarde horn loudspeakers (Germany) and electronics from Art Audio and Gill Audio Design (US).

Jim Smith (US-Avantgarde Importer/Distributor) and Casey McKee, Natl. Sales Manager, were present representing the loudspeakers, and from Art Audio and Gill Audio Design were Joe Fratus and David Gill. The equipment we listened to were the Avantgarde Trio speakers, their top-line model, Art Audio’s Jota mono block amplifiers and PX-25 stereo amplifier.  The Gill Audio Design "Alana" line remote control preamplifier and "Elise" 24 bit/96K DVD compatible D to A converter were also auditioned. All of these pieces are completely tube, except for the Burr Brown 'J' D to A chip sets in the converter. The amplifiers are all single ended. The Trio’s include three horn drivers and two SUB225 CTRL PRO sub-woofers per channel. These are powered by dedicated, internal 225 w solid-state amplifiers with gain and xover freq. controls. Each woofer has a pair of matched 10" drivers w/19lb. magnets.

The members were first given the opportunity to listen to the Trio’s driven by the new Jota mono-blocks featuring the new < face="Courier New" size=3>Czech 'KR' 300B XLS (a bit more on the tube later) rated at a minimum of 17 w depending on the loudspeaker impedance characteristics. The Trio's are so efficient(> 107 dB)they appear to run on air. One watt is usually sufficient in a reasonable size home listening room. At $37K per pair, the Trio's are quite a statement, and in this case beautifully finished in Audi automotive finish, light metallic green. Most automobile finishes are available, and according to Jim Smith, Red is the best seller.

The first CD recording was an acappella choral group singing gospel music, whose lead singer had a great bass voice (The Fairfield Four). They were there with us, in the room, so it seemed. When the first bass note was hit by that bass, it was incredible, and very real. I have sung in church choirs for years, and it was impressive! This piece was followed by other acoustical and choral music, and it sounded great. My thoughts were very detailed, realistic, dynamics like real music, effortless sound presentation and immense soundstage.

Our first speaker was Joe Fratus of Art Audio (RI). He described his design philosophies and the history of Art Audio. He mentioned that all the mono block amplifiers are built "to spec" for each individual customer, after the customer tells them what will be driving the amps (preamp, etc.) and what the amps will be driving (what type and brand of speakers). In this case were the first public group to hear the new Czech sourced 'KR' 300B XLS high-current power tube that can effortlessly output 17-to-20 watts of pure class 'A' RMS power all day long without breaking a sweat. This new, 6" H "Coke Bottle" envelope tube is a wonder to hear and behold. It sports a massive '+' shaped plate that's able to handle this extended power not normally expected from a 300B. And this bad-boy indeed does it, while preserving musical textures across the audio spectrum.

We were then introduced to David Gill of (you guessed it) Gill Audio Design of Raleigh, NC. This company is a "sister" company of Art Audio, which will concentrate on "digital" electronics, using tube analog sections. Gill also described the details of the "Alana" preamp and the Elise D to A converter.

After a break and listening to more music, Jim Smith spoke about the Avantgarde speakers. He gave us a brief history of his 30+ yr. audio career - since the 1980's and 90's he has been in the "real high end". He and Casey McKee, of Austin, TX are long time compatriots in the pursuit of the world's best audio and it seems they're indeed remaining on-track. Jim (formally operating out of Birmingham, Ala), is now based in Cumming, Georgia (how convenient not far north of Atlanta – that is where yours truly resides). He told us that the speakers really shine when set up properly and would welcome anyone to come on over and audition them in his setup. They sounded pretty darn good in the room we were in! And indeed this is a pretty difficult and large room to cope with, especially with only a few hours to acclimate the system. None of the presenters had ever seen or set-up a large complex system in this room. Indeed, hats off to this whole team.

Last but not least, we listened to the speakers driven by the PX-25 stereo amplifier. This 6 watt per channel single ended amplifier had no problem driving the speakers to "realistic" levels as we listened to the latest release of the Atlanta Symphony Orchestra. Even though the tubes were not fully broken-in, again, the music was with us in spades. It sounded as good as I have heard them play in Symphony Hall. Of the two amplifiers auditioned, the new Jota mono-blocks appeared to  be the favorite by it's rich and robust presentation.  It also seems that the PX-25 was not fully broken-in.  In any case, it was all a lot of fun and long remembered.

Another great program, and our thanks to all who worked so hard and traveled so far to put it on!
