AXPONA 2010

In addition to his enormously impressive hi-rez surround-sound dem mentioned earlier in this report, Mark Waldrep of AIX Records and iTrax.com gave a well-attended seminar on all three Show days explaining how a computer can be used as a valid source in a high-end audio system and demystifying HD music.

Jim Smith, author of Get Better Sound, spent a full hour discussing a host of topics from his book. Among the subjects he was prepared to cover were optimal use of subwoofers, loudspeaker set-up, multi-channel system requirements, room acoustics and treatments, system enhancements, bi-amping, and analog vs digital. In the brief time I spent in the room, questions were lively and plentiful. One in particular, on compression in modern pop recordings, harked back to John Atkinson's recent "As We See It" and his Rocky Mountain Audio Fest presentations on the subject.

Since the first Show in which I was involved in the organization (the 1981 Hi-Fi News Show at London's Heathrow Airport), I have arranged a program of seminars where Showgoers can be entertained and also learn more about the theoretical aspects of audio. Axpona was no exception, and for the very first seminar after the Show opened on Friday afternoon, my guests were Mark Waldrep of AIX and iTrax.com (left) and legendary mastering engineer Bob Katz, of Chesky fame and many others (right). We spent 75 minutes talking about the advent of the computer as a high-end audio source, the sonic advantages of high-resolution audio, and the sonic limitations of lossy compression. My thanks to Mark and Bob for taking part, and also to Michael Fremer, Jason Serinus, Jim Smith, John MacDonald, Dick Diamond, and Bill Dudleston for giving up some of their time at Axpona to talk to Showgoers at these seminars.

Jason already blogged about the sound from the big rig in the Cary Audio room, which was being run by Florida retailer Let There Be Sound. I had enjoyed the sound of Ry Cooder's classic Jazz from LP in that room Saturday night after the Show closed, as well as a CD-R of songs from the Who's Tommy, burned from an acetate of the master by Mikey Fremer using his awesome Continuum record player. But Sunday morning, LTBS's Oswaldo Martinez was playing Rebecca Pidgeon's classic "Spanish Harlem" from CD on a system featuring the 5Wpc Cary Exciter integrated amplifier driving these beautifully finished single-driver bookshelf speakers, the Sur. Pidgeon's voice sounded smooth and natural, the double-bass accompaniment evenly balanced and more extended in the lows than I was anticipating, though when a Showgoer asked for The Doors' "Waiting for the Sun" to be played, the electric guitar sounded a little peaky in the mid-treble. To be priced at $2000/pair, the Sur features a port-loaded, full-range Fostex drive-unit and will only be available from LTBS.

In the aptly titled Navigator Room, Fernando Cruze of cruzeFIRST Audio of Miami had quite a stunning display of gear imported by Chris Sommovigo of Atlanta. At its head was the fabled Continuum Audio Labs Caliburn LP system ($150,000), equipped with a Lyra Titian I cartridge ($5800) and Chris' own tonearm cable. Sending its signal via the two-chassis Audio Premier Quattro preamp ($15,000) and Belles SA-500 stereo amplifier ($9000) to the Lansche 4.1 loudspeakers ($55,595/pair) with their plasma tweeter, 25Hzצ150kHz capability and extreme 99dB sensitivity, the system also benefited from two Tri-Point power conditioners, the Troy ($12,000) and Spartan ($35,000) and a full complement of Stereolab cables (loudspeaker, $3750/2.5m, interconnect, $3500/1m). If you can say that all in one breath, and pay for it without blinking your eyes, more power to you.

Speaker designer Bill Roberts talks so fast, I could only write down every third word as he explained the design principles behind the Advanced Transduction Directorate loudspeaker. A four-piece, three-way system with an outboard crossover and line-loaded woofers, the 600lb Directorate has a very high claimed sensitivity of 96dB/W/m and bass extension of –3dB at 14Hz. Price is $30,000/system in light-oak veneer, or $25,000/system unfinished, as shown in the photo. With left and right speakers each driven by a 125Wpc Power Modules Belles 150A Reference stereo power amplifier ($2300), and a front end of CD files played with Sony Sound Forge running on a PC sent as digital audio to a Belles DAC and the new tubed Belles 22A preamplifier ($2500), the sound, even in an acoustically challenged room, had superb balance, dynamics, and transparency.

As you will see from the forthcoming May issue of Stereophile, modern horn speakers don't suffer from the colorations and idiosyncrasies that plagued the genre in earlier decades. Such was the case in the room shared by Aaudio Imports and Sanibel, FL retailer Lee Island Audio. The German Acapella High Violoncello II speakers ($80,500/pair) with their ionic tweeters, driven by Einstein The Turntable's Choice phono preamp ($9,800), Einstein The Tube Mk.2 balanced line stage ($18,400), and a pair of Einstein The Final Cut tubed OTL monoblocks ($34,900/pair), connected with Stage III interconnects, speaker cables, and AC power cords, produced a seamless soundstage and a smoothly coherent tonal picture. With the LP of Rickie Lee Jones singing "Chuck E's in Love," played on a Galibier Stevio turntable ($15,000) fitted with a Triplanar Mk.VII tonearm and a Dynavector XV1s phono cartridge ($5250), the sound was one of the best I heard at Axpona. I have asked Aaudio Imports' Brian Ackerman for review samples of the Acapella speakers.
