There was a lot to see in the Lenbrook Group rooms and I was pleased to see that the anticipated T-175 multichannel pre-pro was ready for prime-time. However, the unit that caught my eye was a little stereo unit, the T-715. This trim, $499 beauty has a 25Wpc amp, a CD player, an AM-FM tuner, and a subwoofer output in addition to the usual audio line-level inputs and outputs and headphone jack. It also sports a USB input for playback of MP3s or of anything streaming off the Internet. It's just about the size of a shoebox. Add a pair of small speakers, like PSB's $279/pair Alpha B1s, and you have an ideal and compact second system.

Similar to the MPC line level terminations are MIT's Multipole In-Wall termination systems, shown here by Kent Loughlin. The five-way binding posts fit into an ordinary on-wall quad box and come in three configurations: 11 pole, 15 pole, and 21 pole network. No soldering required.

Canton's chief designer Frank Göbl proclaimed the new, improved Vento line "better—not a lot better, but significantly." What's new and improved?

A beaming Gregg Dunn hailed me over to the Cary booth and said, "I know what you are looking for!" He was right. In his hands, he was holding the new Cary Cinema 11V, the video-input/processor that mates with the Cinema 11 (now 11A) audio-only pre-pro that I found to be a really wonderful performer in my July column. What the 11V adds is a useful array of video (and audio!) inputs and outputs but, most significantly for audiophiles, it strips the hi-def audio content from HDMI inputs and pipes it through a proprietary digital connection to the 11A. Add an RS232 connection and the two are linked to work as one, although they can function independently. Specs are decidedly cutting edge, with six HDMI 1.3 inputs and capability for 1080p video at 120Hz!

I got a chance to listen to a 5.1 setup of small HM series monitors ($1699 each) from Adam Professional Audio, the same speakers that the recording had been mixed on. Even amidst the hustle and bustle of the CEDIA floor, they made a good showing. Even more impressive were the new Tensor series, all of which use ART (Advanced Ribbon Technology, inspired by the old Oskar Heil ribbons) HF and MF drivers, along with active Hexacone woofers in substantial cabinets. The larger Beta and Alpha models have additional cone midrange drivers. All are also available in fully active versions and the line runs from $8199 for a semi-active Gamma to $24,999 for a fully active Alpha. Klaus Heinz proudly explained his design philosophies, but the show floor was no place to really appreciate the speakers' performance. These look really promising.

MIT's Bruce Brisson was determined to shrink his Multipole technology so that his patented networks did not requite bulky boxes near their cables' termination. Naturally, he thought surface-mount components were the way to go. That was until he began measuring them and discovered that SM components were variable and many didn't measure well.

Canton's Frank Göbl is a busy little beaver. He wondered what it would be like to put the components of Canton's successful Ergo line into new specially designed cabinets that could bring the prices down by 30%. "Cost efficiencies have enabled us to do this without sacrificing sound quality or beauty," said Canto USA president Paul Madsen.

We get a kick out of Paul Barton, so we wandered into PSB's room to see what's new. He was talking to a good-looking man of a certain age (ours, approximately), to whom he introduced us: it was Vance Dickason, the man who wrote the book on designing DIY loudspeakers: The Loudspeaker Design Cookbook.

Joe Harley was striding around the Denver Convention Center. When we shook hands, he glanced around and said, "Let's go somewhere private." We ducked into an empty demo room and he pulled a few records out of his bag. "Nobody else knows about this, I'm giving you the exclusive."

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.

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 decided that since Stereophile only had two show bloggers this year, I would avoid writing about weird custom-install products and home-theater systems. However, rules, as they say, are made to be broken.

Billed as the "world's first audiophile music server," the MS250 contains a 400GB hard disk and a CD ripper/player, as well as "a custom sound card specifically designed for the MS250 using four Crystal CS4398, 120dB dynamic-range, 24-bit, stereo DACs, plus properly implemented power supplies and output filters, just like an Arcam CD player."

It was disorienting to arrive in the Denver Convention Center and both have to re-learn where everything is and to try to maintain my bearings on the Show floor. The grid of floor sites is very approximately regular, with each numbered row thickening and thinning to complement its neighbors. At one point, I had let myself be led around to three different booths by a press representative, only to look up and not know which was the front and which was back!

Marantz was showing some heavy metal: Its new line of reference components, which will only be available at select dealers. Shown here are the SA-11S2 SACD player ($6999.99), the SA-7S2 stereo control preamplifier ($7999.99), and the MA-9S2 monoblock power amplifiers ($7999.99 each).
