I start my second report from the 2010 CEDIA Exposition by returning to MartinLogan. As well as their $2000/pair ElectroMotion electrostatic hybrid that I described in my first report from CEDIA, the Kansas company showed the appealing new 2-way Theos. This hand-built floorstander combines a 9.2"-wide by 44"-tall XStat electrostatic transducer with a 8" aluminum-cone woofer in a bass reflex enclosure. Its large electrostatic radiator and passive woofer can be bi-wired or not with a unique tool-less binding-post design. At $5000/pair, the Theos will be the most affordable speaker in the Reserve Series of floorstanders.

Back in Atlanta's World Congress Center for the second year it is hot (around 90°F) and humid outside but it is cool at the 2010 CEDIA Exposition. On the very first full day, I found a slew of interesting new loudspeakers and that's despite having seen less than a third of the Show floor. Undoubtedly more will be discovered but it is great to say that all of the most intriguing new ones are relatively inexpensive.

The debate over which audio component is most important in determining the quality of a system's sound is one that has been with us for decades. Recently, it came up in a conversation I had during a visit to a Manhattan high-end shop, when I was told about a discussion on the topic by Ivor Tiefenbrun (of Linn) and David Wilson (of Wilson Audio Specialties). You don't have to be a seasoned audiophile to predict their respective positions, but when I was pressed to take a stand, I paused.

I've been enthusiastically tracking the development of Bel Canto's class-D amplifiers, from their original TriPath-based models to their more recent designs based on Bang & Olufsen's ICEpower modules. With each step, Bel Canto has improved their amps' sound quality and reliability.

For the past few years, PSB Speakers International has been replacing its older lines with new models designed in Canada, and assembled in China from Chinese-made components. Judging from the reception here of PSB's Synchrony One and Imagine T, it's clear that the new models combine advanced performance with true economy. Now, with the new Image line, we see the result of trickling all this down to less expensive products.

I was greatly impressed by the performance of the Canton Reference 9.2 DC loudspeaker, which I reviewed in the March 2008 "Music in the Round" in the context of a 5.1-channel system. Those beautiful jewels not only sounded balanced and transparent, they had more sheer grunt in the low end than could be reasonably expected from their size. I wanted to hear more from Canton, but couldn't decide whether to go up in size or down in price. The problem I've always had with Canton is that they offer such a wide range of products that it's like choosing food from a multipage menu at a fine restaurant: everything looks good. It's especially difficult when your hunger is further piqued by your own past experience and the recommendations of others. (Check out the November 2006 issue to learn how much Wes Phillips enjoyed Canton's flagship speaker, the Reference 1 DC.)

An audio/video receiver in Stereophile? Heresy!

It was only a few months ago that I greeted Oppo Digital's BDP-83 universal Blu-ray player as a breakthrough consumer component, and it became a Runner-Up for Stereophile's Budget Product of 2009. It now appears that Oppo is using the design as a base on which to develop similar and more advanced products, both for themselves and for a good many other manufacturers. Some may take exception to my use of the word manufacturers—if it's an Oppo under the skin, what, precisely, are these other "manufacturers" contributing? Well, that's hardly a new question.

It seems only yesterday, but it's been 10 years since I began using the original Paradigm Reference Servo-15 subwoofer in my system. It was good then, and it still is, although a lot around it has changed. At first, I hooked it up via Paradigm's X-35 crossover, then via a Technics SH-AC500D surround processor, and finally to the subwoofer/LFE outputs of the various preamplifier-processors and A/V receivers I've used. Y'see, the Servo-15 is just a powered sub. It has an amp and a level control, but no crossover, no channel mixing, and no phase control. Just plug in the signal and it plays it. Along came in-room response correction from Audyssey, Anthem, Velodyne, etc., and the Servo-15 became an even better sub. For music, it entirely satisfies my needs.

It began when my oldest brother, 13 years my senior, returned from military service and told me about "hi-fi." Until then, all I'd known was our ancient tabletop radio-phonograph with its insatiable appetite for osmium styli. Back then, in the early 1950s, audio componentry was scrappy, still evolving from World War II military electronics and public-address systems. I began reading the electronics magazines and learned that, to get started, I needed a record player connected to an amplifier and a speaker. I toured the shops and stalls on old Cortlandt Street, before the building of the World Trade Center, and made my selections based on appearance, reputation, and specifications rather than on sound. Still, compared to what we were used to, the results sounded hair-raisingly good.
