LATEST ADDITIONS

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.

Soulution Audio's Cyrill Hammer was on hand to discuss the company's "small" Soulution 501 mono Amplifier ($55,000/pair). Similar in design to the Soulution 710 stereo amplifier that had so impressed Michael Fremer in the August 2012 issue of Stereophile, the more diminutive 501 monoblock amplifier is rated at 125W into 8 ohms, utilizes six switching-mode power supplies, and features a high-bandwidth, zero-feedback voltage-amplification input stage. Unlike the 176 lb Soulution 710 stereo amplifier that required three good men to move into Mikey's listening room, the 501 weighs in at a "mere" 80 lbs per 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.

Luke Manley and Bea Lam of VTL were on hand as host and hostess at the VTL exhibit suite at the Venetian Hotel to present their two new stereo tube amplifiers, the $33,500, 400Wpc S400 Series II amplifier, and the $10,000, 200Wpc S200 Stereo Signature amplifier shown in the photo. Although the S400 was configured into a floorstanding tower and the S200 in the rack-mounted chassis used for their MB-450 monoblock amplifier, both new products feature VTL's latest tube technology, including fully balanced, differential input stage, VTL's SmartTube technology with automatic bias and screen supply adjustments and fault sensing, and a new user-adjustable damping factor feedback control. The feedback loop amount can be precisely set to suite the listener's taste via three-position switches located between the input tubes on the top of the chassis.

Joseph Audio's Jeff Joseph is always a smiling, positive presence at CES and other shows, and always seems to have something new in his speaker line, even if "new" is defined as "finally in production." This describes the Perspective ($11,800/pair), making good sounds with relatively affordable Bel Canto equipment ($2995 digital receiver and CD3 transport). The tie Jeff is wearing has cartoon figures designed by Joshua Joseph, Jeff's 11-year-old son.

I know of speakers where, depending on the crossover, the same 5" or 6" driver is used as midrange or as woofer, but I've never encountered a speaker where a driver normally designated as a tweeter also functions as a midrange. This is the unusual design approach taken by McIntosh in some new speaker models, including the $10,000/pair XR100, and, judging by the sound, it certainly works for them. The driver is a 2" metal dome: eight of these are combined to serve as midrange, with two more as the tweeter flanking a supertweeter.

Atlantic Technology's AT-1, which uses their patented H-PAS venting technology, was one of the hits of last year's CES, and the positive impression was confirmed in Erick Lichte's review (September 2011). The H-PAS approach has now been applied to the new AT-2 ($1800/pair). The –3dB point is specified as 41Hz, which I'm told is an anechoic figure. This normally translates to in-room response to the low 30s, and the sound of the AT-2 in the Venetian's less-than-ideal space seemed to confirm this.
