Thiel and Bryston always share an exhibit area in the Sands Convention Center’s Bassano Ballroom, and this year's CES was no exception. James Tanner, Bryston's upbeat product manager, had gathered a terrific playlist of musical selections on a thumb-drive, which drove the company's $2195 BDP-1 digital file transport, $2195 BDA-1 DAC. Livingston Taylor's whistling on "Isn't She Lovely" opened the playlist, just as it did at the Joseph Audio suite, and many others—it was a common selection at the Venetian exhibits. Sound from the $9500 Bryston SP-3 preamp/processor ($7900), three-channel Bryston 6BSST2 amplifier, Thiel CS1.7 speaker prototype and Thiel USS SmartSub Subwoofer produced soundstage depth and imaging that was among the best, almost as good I heard at the much more expensive system in the VTL suite. Tanner walked me through Bryston's newly announced BHA-1 headphone amplifier featured in the photo ($1295), which is highly versatile, including twin XLR outputs for balanced headphones, and both XLR and ¼ jacks for conventional headphones.

In response to Mark Levinson Audio Systems' 40th Anniversary, the company has announced a new line of products for the two-channel audiophile, the 40th Anniversary Collection at CES 2012, which includes the $25,000 No.52 Reference dual-mono preamplifier, the $10,000 No.585 integrated amplifier, the $6000 No.519 SACD player and the $6000 No.560 digital processor. I was most intrigued by the $10,000 No.585 integrated amplifier shown in the photo, which is rated at 225Wpc into 8 ohms, and provides a dedicated subwoofer output.

Harman Specialty Audio's Kevin Voecks demonstrated his latest portable room-response testing system, an iPad 2 running Studio Six Digital's "Audio Tools" iTunes app. (A favorite of JA’s.) The iPad 2 plus a $50 external mike and an accessory box from Studio Six becomes a portable audio test system with up to 1/48-octave resolution. Kevin used this tool to set up Revel's new M106 and F208 loudspeakers on the 35th Floor of the Venetian Hotel. He demonstrated frequency response graphs and a virtual SPL meter—seen in detail as a graphic representation of a huge analog SPL meter on the iPad screen.

It was good to visit McIntosh Laboratory's 35th floor suite at the Venetian Hotel and spend a few minutes with Ron Cornelius, the product manager, discussing our shared experiences with the legendary McIntosh MR-78 FM tuner. Ron showed me the latest iteration of the company's MC-275 tube amplifier. Now released as version 6, 50th-Anniversary 275, priced at $6500, it reminded me that the amplifier was first shipped in 1961.

Sumiko teamed up a pair of Sonus Faber Amati Futura floorstanding speakers — watch for JA's review in the March 2012 issue—with the $4500 REL Gibraltar G1 subwoofer to produce explosive, massive, but tightly controlled bass while playing the "Chinese Drum Poem" selection from disc 3 of the Burmester Demonstration Disc series. The REL G1 is a 108 lb, closed-box, front-firing 12" driver driven by a 600W, high-current amplifier. Sumiko's John Hunter set the gain of the G1 using a small remote. The G1 subwoofer fell totally silent when the music was free of deep bass content, as it should.

Not to be outdone by the audiophile crowd, an auto sound manufacturer displayed a huge metallic woofer that dangled from a crane. (The crane could be set to lift loads between 500 lbs and 3 tons.) I thought I had seen everything, but the North Hall of the Las Vegas Convention Center never disappoints!

Ron Sutherland had a rack of his components at CES to drive Vandersteen Quatro floorstanding loudspeakers. The rack consisted of the two monophonic Phono Block phono preamplifiers, recently reviewed by Brian Damkroger in Stereophile; the $15,000 Destination Line Stage (one non-audio signal carrying control unit with Nixie tubes, and one audio chassis for each channel); and the $10,000/pair, 200W monoblock power amplifiers. Except for the amplifier and control chassis, most of these units are configured into two side-by-side subunits—one for power supply and one for audio signal—attached only by front and rear panels.

The $25,000, 500W Mark Levinson No.53 digital-switching reference monoblock amplifier made its regular non-playing appearance at CES 2012 but this time with an illuminated cutaway display, allowing its lead design engineer, Mark Seiber, to walk me through its circuitry. The transparent panel, which the display used in place of heatsinks allowed me to easily see the No.53's four major subsections (analog input stage, modulation, amplifier output stage with its eight air-core inductors, and power supply section, which is at the bottom of the chassis.

Harman Specialty Audio introduced the new Revel Performa 3 series of loudspeakers at the 2012 CES. Kevin Voecks, lead audio engineer in the design, was delighted at the increased performance of Performa 3 series, including the $4500/pair, three-way, F208 full-range floorstander and the $1750/pair M106 two-way bookshelf. The F208 replaces the more expensive, $7500 F32 Performa in the previous series.

Brent Hefley, Marketing Manager of Ayre, walked me through the circuit layout of Ayre's newest amplifier, the $14,950, dual-mono, 200Wpc (8 ohms) VX-R. Based on the well-regarded and long-established MX-R monoblock and introduced at the 2011 CES, the VX-R uses Ayre's ultra-fast printed circuit board materials. Ayre is expecting great things, Brent told JA, from its recent hiring of ex-Classé and Linn engineer Alan Clark, who joins Charlie Hansen and Ariel Brown as the Colorado company's creative engine.
