In my opinion, the relation between speaker size and performance tends to be a curvilinear one: performance improves with size up to a point (assuming good design), but when speakers are really big they’re often disappointing, sounding merely "impressive" but not natural. I’m always delighted, therefore, to find an exception to this rule, and that was the case with the PBN Audio Montana Master Reference speakers at the outboarding THE Show at the San Tropez Resort. These speakers are 84" tall, weigh 500 lbs, and feature two 18” subwoofers, two 10" woofers, two 5.25" midrange units, and one 1.125" tweeter. Demoed by PBN President/Designer Peter Noerbaek and Vice-President Patty Noerbaek, these speakers, driven by PBN's own amplifiers, sounded impressive and natural. The price is $65,000/pair, but you do get a lot of speaker for the money. Peter Noerbaek says they sold four pairs last year—to people with baronial homes, I’m sure.

Ypsilon Electronics was a new name to me, so I wasn't sure what Jon Iverson and I would see when we entered its room. Whatever we expected, it wasn't the <I>ginormous</I> hybrid SET-100 monoblock amplifiers ($69,000/pair).

Ray Kimber's isoMike demonstrations always deliver some of the most natural sound of any show he attends&mdash;and CES 2007 was no exception.

"Let's face it," Neosonik's Ted Feldman said, "wires are a hassle&mdash;nobody really wants to clutter up their homes with the darn stuff. I know eliminating wires has always been a dream of mine."

Von Schweikert Audio's VR-5 SEs ($25,000/pair) aren't new, but once again they impressed Jon Iverson and me with their verve and natural presentation of acoustic guitar. Nils Lofgren's "Keith Don't Go" kept us nailed to our seats for the whole 12 minutes&mdash;which, in CES Show mode, is equivalent to seven human years.

Joseph Audio's Jeff Joseph didn't bring any new goodies to the show this year. He once again demonstrated the $2495/pair Insider. "I'm still trying to demonstrate how incredible an in-wall loudspeaker can sound&mdash;if it uses an infinite slope crossover, that is."

Paul McGowan's $2500 PS Audio Power Plant Premier is radically different from his earlier power regenerating products. "For one thing, it's 85% efficient, which means it runs cooler and uses less energy," McGowan explained. "It has 10 Power Port receptacles with Nano Crystalline filters. It's even remote controlled."
