Audio Note UK's David Cope always does good dems at shows, and AXPONA was no exception. With the K/SPe two-way, sealed-box speakers ($3700/pair plus $650/pair for stands) placed in the room corners, and driven by the OTO SE Signature parallel singled-ended integrated amplifier ($5500; $6300 with phono stage), Lukas Foss's Time Cycle, a 1960s recording from Leonard Bernstein conducing the Columbia Symphony Orchestra, sounded rich yet detailed, with percussion instruments nicely delineated in space. David then played a familiar CD, Cantus singing "Swing Low, Sweet Chariot," which I had recorded 10 years ago. This revealed the system to sound a little too lush and warm, but who could complain about that!

Toward the end of the final day in Las Vegas, I found Kalman Rubinson entranced by the sound of Shirley Horn singing and playing piano in the Audio Research room at T.H.E. Show. A pair of the new Mk.2 version of the Wilson Sophia speakers was being driven by ARC's Reference 210 monoblocks, a Reference 3 line stage, the Minnesota company's new Ref CD7 player, with cables from Shunyata and Cardas and AC conditioning by Richard Gray. I was equally entranced.

"The only tubes that I want to see in my household are...the picture tube in my TV and the magnetron in the microwave oven," a Glendale, CA, reader recently wrote, and I guess his feelings reflect those of many when confronted by a supposedly "obsolete" audio technology. Forty years after the invention of the transistor and 20 after the widespread introduction of solid-state amplifiers (footnote 1), it must come as a shock to readers of the mass-market "slicks" that not only do a number of American manufacturers manufacture amplifiers and preamplifiers using tubes, but some of those companies—Counterpoint and Audio Research in particular—are among the more successful. It is the Classic 60 power amplifier from Minnesota-based Audio Research that is the subject of this month's lead-off equipment review.

Some manufacturers weren't exhibiting at CES but did have suites elsewhere in the Venetian hotel. One such was Audio Research, who was showing the first amplifier to be designed following the passing of the company's long-time Senior Design Engineer, Ward Fiebiger, who died of a heart attack last March. The Ref160M monoblock offers around 150W into 8 ohms and will cost in the region of $30,000/pair.
