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.

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.

Paul Stookey, now 74 years young, sounded optimistic, vibrant, and sweet, delivering a solo performance to the audiophile crowd at the Flamingo, as hosted by T.H.E. Show, Cary Audio, and PBN Audio. Somehow Paul has retained all the youthful energy and optimism that characterized his role when was a member of the Peter, Paul and Mary trio. Although I associate him more with the flower child, utopian, flower-child world of the 1960s, celebrating love, sex, freedom and occasionally drugs ("Puff the Magic Dragon"), he easily slipped into the role of audiophile troubador. Although his vocal range had narrowed with the years, his guitar accompaniment was superb.

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.

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!

The Audio Power Labs exhibit took my breath away, Imagine, a huge, beautiful $175,000 per pair, 200Wpc monoblock tube amplifier using 833C, graphite-plate, radio-frequency transmitter tubes that have a bandwidth of 30MHz and run with 1500V on the plates! These tubes were used in the output stage of BCF-1 radio transmitters. Now imagine that the amplifier's designers are named Squeek Rieker (right) and Peeya Iwagoshi (left), and you know why I had to pinch myself to make sure I wasn't dreaming.
