Rives Audio is repeating a demonstration that was a hit at last year's show in Los Angeles. Two rooms are set up with near identical systems. One room is completely untreated, the other uses a variety of acoustical treatment devices plus electronic equalization of the bass (using two Rives Sub-PARCs and extra amps to support the equalizers). The speakers in both rooms are Talon Thunderhawks ($25,000/pair), the amplifier the VAC Alpha Integrated ($10,000, an all-tube design with 100Wpc), and the CD player the Wadia 580i ($9450).

Silverline was demonstrating two different speakers, the floorstanding Prelude ($1200/pair) and the small Minuet ($600/pair). I heard the Preludes ($1200/pair). One attendee remarked that the Preludes sounded better than a lot of more expensive speakers at the show. Apart from a trace of aggressive brightness, which could well have been due to a completely untreated room, I have to agree. The speakers sounded more dynamic, and bigger, than their size might suggest. Silverline makes a wide range of speakers, including a center channel (which at $1200, may be a little pricey to mate with the Preludes).

Two makers of one-box solutions for virtual surround sound were at the show. ZVOX was covered earlier in our show report (below). Soundmatters is the other. The Soundmatters SLIMstage40 Surround Console ($899, available in July), available in either silver or black (the silver version is shown in the photo, just under the flat panel set) uses four seven active drivers and eight internal amplifiers (170W total) to simulate a full surround sound experience. At 3.4" deep, it's designed to fit under a wall-mounted, flat panel television.

One of the interesting new features of this year's show is a variety of workshops, many of them to be presented more than once throughout the show. There are workshops on amplifier measurements, amplifier listening, speaker auditioning, speaker measurements, the peak power demands of music, and active loudspeakers. The Stereophile Analog Clinic also continues, as in past shows.

I've got to hand it to Nicoll Public Relations. Not only do they represent a lot of our favorite manufacturers, like Meridian, B&W, and Silicon Optix, they're also responsible for supporting the press during our Home Entertainment shows, and YES, that basically means feeding us.
