JA’s Best Sound at CES: Vandersteen’s Model 7 Speakers
The Naim/Focal, Marten/Pass Labs, and Sony/Pass Labs exhibits got close to the Vandersteens in absolute sound quality, and all were even better in some respects. But none were quite so musically perfect across the board!
Designed with engineer Dean Klinefelter, the M7-HPA provides a high-pass filtered output (above 100Hz) to the upper-frequency drive-units of the Model 7, which has an integral powered subwoofer. The amplifier uses a tube input stage and two single-ended solid-state output amplifier stages with npn bipolar transistors operating across the speaker load, all mounted in a chassis machined from solid aluminum, with a sprung suspension from HRS and kept cool with a liquid cooling system. Specified output power is 600W into 8 ohms.
