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.

Look at the picture and tell me that those don’t look like speakers! They are, of course, but they are not intended to be driven by audio signals directly. What subwoofer manufacturer Bag End was demonstrating is a small, active bass trap, the E-Trap, and they are driven by the bass frequencies in the room. Each of these small boxes contains a driver, two microphones, and some pretty snazzy electronics that let the driver cancel the energy at the frequency (or two) of your room’s major mode. Sure, acoustic treatment is generally best, but that can get awfully cumbersome below 100Hz. Adjustments allow you to select frequencies between 20Hz and 65Hz and adjust the amplitude and shape of the cancellation. For critical success, you need to experiment with placement (although that is almost always at a room boundary) and, at the moment, have access to some nice FFT software. Bag End's James Wischmeyer promises that, eventually, some simpler setup software will be provided. Mebbe, but I asked to try one ASAP.

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.

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.
