I finally got a chance to look at, but not yet hear, Bryston's first venture into a source component, the BCD-1 CD player. James Tanner gave me a tour of the innards which were even more impressive than the beautifully carved front panel and sturdy disc tray. He said that, while they used a Philips transport, all the control electronics were replaced by discrete Bryston-designed drivers and DACs and that separate transformer windings powered separate power supplies for the transport and audio electronics, with multiple isolated and regulated supplies for individual circuits and channels. That allows the class-A output stages to function best. In addition to the analog outputs, transformer-coupled S/PDIF and AES/EBU digital outputs are provided.

Pioneer showed a number of interesting new products in two-channel electronics and speakers. but pride of place was ceded to their new flagship A/V receiver, the SC-09TX. This is almost, but not quite, a pair of separates with the 10-channel, ICE-powered class-D amp confined to a chassis separated from the rest of the digital and line-level electronics. The main 7 channels are rated at 200W, operated simultaneously. I thought it notable that the amplifier chassis is configured to be under the main chassis and that indicates that we’ve reached a point where the efficiency of class-D amps allows the power-hungry DSP and video processing to breathe out the top. Fans help, too. Every conceivable input and output is provided including 6 HDMI inputs and two HDMI outputs, accommodations for XM, Sirius, and iPod input, and a talented EtherNet link. I show you the back panel to impress you with the connectivity and the distinct chassis for the power amp. The front panel sports a 4" LCD for control and video previewing.

I've been reading and sometimes participating in a number of Internet discussions that begin with something like "Is SACD (and/or DVD-Audio) Dead?" Regardless of your one-word answer, it seems that the issue is still quite lively. I won't address the question here (you know where I stand), but it almost doesn't matter. Many high-resolution multichannel recordings are still being made. It's just that they may be distributed in different ways.

I hate all those automobile reviews that go on and on about a car's design aesthetics. C'mon, I can see what it looks like, even if only in the pictures. Just tell me things I can't appreciate without a run on the Autobahn.

Good things come in threes, they say. Well, three-channel power amps suit me just fine. My main component rack is at the back of the room, so I split power duties between a two-channel amp under the rack to drive my rear-channel B&W 804S speakers and, way at the front, either three monoblocks or a three-channel amp for the front three B&W 802Ds. I do this to ensure that the timbre of the front three channels is consistent. The outstanding performance of the Simaudio Moon W-8 dual-mono power amp (Stereophile, March 2006) almost tempted me to go with a stereo amp and a monoblock, but voicing and balancing a multichannel system with equanimity makes me want as much simplicity as possible. I guess manufacturers and users see it the same way; many new three-channel amps are coming on the market.

More than a decade ago, I bought a new pair of speakers and sought to find the most suitable cables for them. After auditioning a number of borrowed sets, I enlisted my daughter to confirm my selection. She grew up in a household where there was always good music playing on good equipment, but had no active interest in either. To placate Dad, she listened to a few of her own recordings with each of the various cables and then, lo and behold, reached the same conclusion I had. In fact, she described the differences almost exactly as I would have. I was ecstatic. Not only did it confirm my opinions about the cables, but it confirmed to me that any motivated listener can hear what golden-ear audiophiles obsess about. As I tried to express my joy to her, she left the room with this parting shot: "Yes, of course, but who cares?"

My first exposure to Burmester electronics was some years back at a New York Hi-Fi Show, where they were powering a pair of B&W 801s and impressed the hell out of me. But Burmester's distribution seemed sporadic and the prices beyond my consideration, so I put them out of my mind.

My reviews of the TacT RCS (Stereophile, September 2001) and the Rives PARC (July 2003) are ample evidence that I've been fascinated with room equalization for quite a while. This is because I don't have a dedicated, purpose-built listening room in either of my homes, and having experienced what such rooms can do for recorded sound, I've always been somewhat dissatisfied with what I do have. Sure, I've got lots of great equipment, and a wife who understands enough to let me install some acoustic treatments (as long as she approves their appearance). Still, I'm sympathetic to those audiophiles who, when I suggest acoustic treatments to resolve their particular problems, say that it's simply not possible for them, either because of the Spousal Acceptance Factor or the need to accommodate other activities in the same room. Room equalizers seem to offer the hope for a panacea for what ails such spaces.

Iván Fischer, founder and conductor of the Budapest Festival Orchestra, has performed with many major orchestras and recorded for a number of major labels, most significantly with Philips, from 1995 to 2004. Fischer/BFO made the first multichannel orchestral recording for SACD, which Philips used as a demonstration disc for their first SACD players. I still treasure that disc—it demonstrates many of the advantages of the medium with a wide and varied program—but it has never been commercially released.

One of the highlights of such annual events as the Consumer Electronics and Primedia Home Entertainment shows has been the demonstrations of loudspeakers from TAD, the professional division of Pioneer Electronics. Designer Andrew Jones is always generous in using recordings brought by visitors, and enthusiastic in explaining the technology behind these beautiful behemoths. Among these speakers' unique features are a beryllium dome tweeter mounted concentrically inside a beryllium midrange cone, and a cabinet built of stacked, carved horizontal sections, for incredible rigidity without using exotic materials or excessive mass. The concentric upper-range driver is a reminder that, some time back, Jones worked for KEF, where the coaxial UniQ driver was developed, but the materials and details of the TAD drivers are all new. While the TAD Model 1s are always good for musical and audiophile thrills, their price is in the upper five figures, which put them out of serious purchase consideration.
