The sound in the large PS Audio room was impressive. Despite, at one point, my trying to listen to music over three conversations at once, the system on display,—all PS Audio save for the Avalon Ascendant speakers and JL Audio subs—was distinguished by its full midrange and inviting warmth. The sign on the poster behind the system—"Perfect Power Without the Box"—refers to the company’s forthcoming rack, which will have a power conditioner built into the bottom, additional power filters for every component, and the power itself carried by the tails of the rack. The initial plan is for an 11" wide rack designed for smaller, "lifestyle" components. (I’m one of those folks more concerned with having a life than displaying a lifestyle, but a chacun son gout). A desktop version is also planned.
Jim Rush of PTE (Precision Transducer Engineering) of Orange, CA explained that he was using the system in his room, headlined by PTE’s The Phoenix self-powered, bi-amplified loudspeaker ($5700/pair), to conduct 10 different blind tests with five sequences. The results of his experiments, which he said demonstrated that most people couldn’t discern differences with a high degree of accuracy, are slated to be posted to PTE’s website.
Even if equipment is as excellent as it was in the Eficion/Stillpoints room, no system can sound better than its source material. On that score, I doubt any room save Cookie Marenco's Blue Coast Studios set-up, which was recording acoustic musicians live to DSD, could top Bruce A. Brown's hi-rez files. Bruce's Puget Sound Studios not only does all the mastering for Winston Ma's First Impressions Music (FIM), but also supplies all the 96/24 hi-res tracks for the Chesky Bros' HDTracks site.
To celebrate the 25th anniversary of Purist Audio Design, founder/designer Jim Aud has just introduced their 25th Anniversary cable. Shown at T.H.E. Show for the first time, the 25th anniversary line consists of interconnects ($8100/1m pair) and speaker cable ($18,000/1.5m pair).
“Basically we’re using solid silver, single crystal wiring surrounded by Ferox 103, which is a proprietary doped silicon,” Aud explained. “Our other cables only use copper or copper alloys, and don’t use the Ferox 103.” While Purist still makes two cables that contain fluid, the 25th Anniversary cabling does not.
Welcome to retro city. Not only did the Quad ESL2805 speakers ($10,000/pair), Classic II integrated amp ($6000) and QC24 phono stage ($2449) look from another era, but the equally classic-looking Merrill-Williams turntable ($4000), clamp ring ($649), weight ($249), and 33/45 power supply ($1150) was playing Frank Sinatra's "Days of Wine and Roses."
Tom Compagna brought his new Quintessence Acoustics flagship QLS loudspeakers ($50,000/pair, $60,000 with active subs) to T.H.E. Show. "These are true ribbons, not quasi-ribbons," he said of his SOTA line source design, which uses nine 6.5" true ribbons and nine moving-coil mid-woofers. Frequency response is stated as 39Hz41kHz, ±3dB, extending down to 19Hz with the subs. With a claimed 95dB sensitivity, the QLS can handle up to 400W continuous, 1000W peak. Connected to Tom Maker's reference monoblocks and MG Audio Design flat ribbon cables, the speaker's bass was very impressive, but midrange predominance de-emphasized the top end.
Knowing something about race car driving won't get you a good system in and of itself, but it will help you understand the genesis of the names of Alvin Lloyd's Grand Prix Audio's attractive equipment isolation racks. New is their Woodcote line, the company's first line of wooden racks. Made of true hardwoodno MDF herethe four-shelf cherry model with decoupled shelves costs $4495, and walnut, curly maple, and custom woods are also available.
Unique circumstances conspired to make the March 15 US debut of Raidho's handsome 2.1, 2.5-way floorstanding loudspeaker ($28,000/pair) at AudioVision San Francisco an unusual event. Despite ample planning on everyone's part, US Customs, which has never been known for putting audiophiles first, held up delivery of Raidho's new babies until the afternoon of the demo. Did they perhaps think that the "Raid" in Raidho was code for a terrorist plot?
Due to this unforeseeable snafu, what a very full house of eager audiophiles heard was not the Raidho 2.1 in all its glory, but a literally out-of-the-crate speaker whose drivers, capacitors, and circuits, by all accounts, had undergone only something like 5 hours of break-in. There was nothing that even Nordost's Lars Christensen, creator of the most masterfully conceived and executed audio demos I have ever witnessed, could do about the fact that the speaker could only provide an tantalizing albeit incomplete indication of its ultimate potential.
At the last few Nordost demos I've witnessed, I've been amazed by the huge soundstage, deep bass, and tonal accuracy produced by Raidho's diminutive C-1.0 loudspeakers. Imagine my surprise when I learned that this little speaker, no larger than many a bookshelf design, lists for $18,000/pair. Then again, it produces a fuller, larger, and more coherent image than many a full-range floorstander of comparable price. It also has a pretty even 6 ohm impedance, and is said to be very tube friendly.
