We were stunned to see Roger Skoff in the Ultralink/XLO room—we thought he'd retired years ago. "I did," he explained, "but I was asked to design some new stuff incorporating new technologies and more advanced versions of our existing designs."
We ran into SinglePower Inc.'s Mikhail Rotenberg as he was sprinting down the hall to the Synergistic Research room. "Check these out," he said. "These are a 1932 Tung Argon 4327 and a 1943 722A (323), labeled Centennial, but manufactured by Western Electric."
We're stunned at how few exhibitors spend money for the larger rooms on the 35th floor of the Venetian, since they are so sonically impressive. Sumiko's room with the $28,000 SME 2012, $6000 Audio Research PH7, $10,000 Audio Research Reference 3, Audio Research Reference 210 monoblock amplifiers ($9000/each), and brand-spanking new $25,000/pair Vienna Acoustic Die Musik loudspeakers had us glued to the sweet spot.
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.
