Paul McGowan makes bullshit:

"Four models. One topology — designed by Darren Myers, engineered by Bob Stadtherr. Driven from a state-of-the-art active power supply that delivers performance benefits no traditional transformer-based passive supply can match. Class A bias of 50 watts means your music spends 99% of its time in the most linear region of the amplifier's operation"

Yikes; run the other way ...
