The 2007 Consumer Electronics Show may be officially over, but you can still read our on-going coverage at our <A HREF="http://blog.stereophile.com/ces2007/">show blog</A>.

"Recent advances in solid-state output devices and other components have opened up design possibilities never previously available," Audio Research's Terry Dorn explained. "And <I>that</I> led to our developing the Hybrid Drive HD220 stereo power amplifier ($8995)."

This was our first chance to hear the $8995 Audio Research Reference CD7 CD player. We were impressed!

No, that's not another Vandersteen sock&mdash;it's the carbon fiber plinth of the Vandersteen 5As in Audio Research's room. "Richard [Vandersteen] isn't really offering the 5s in carbon fiber," Audio Research's Terry Dorn told us. "He just wanted to explore the material, so he did these."

At CES 2006, Jon Iverson and I were impressed by Studio Electric's $8500 Type One modules, even though the mating $3500 XLR woofer modules weren't operating. This year Studio Electric was showing off a pair of the $15,500/pair Type Two towers, which were pure art deco chromed metal work.

We were once again impressed by how un-hi-fi the sound in the deHavilland room was, this time in conjunction with a pair of Tannoy Prestiges. The $10,000/pair 50W deHavilland GM-70 single-ended triode is pure class-A, with zero negative feedback. The GM-70's directly-heated triode vacuum tube is said to be the largest output triode available today. We found the sound sweet, but surprisingly detailed and dynamic. Fit'n'finish were superb.

Behold bills itself as "true digital audio" since it maintains audio as a digital signal up to the amplifier stage. The 600Wpc BPA768 (US price TBD) incorporates 768kHz/24-bit signal processing, a switch-mode power supply, an analog output stage, and an integrated power conditioner.

TBI's Jan Plummer is so proud and punched up about his $400/pair Majestic Diamond 1 single driver loudspeakers that he seems to shimmer&mdash;as if he's transporting between this plane of existence and another one.
