It's been a very long time since I had auditioned the Classe 350, for their time they were very nice amps. Smooth and warm with a good degree of clarity and a good bottom end. However, the Pass Labs X.5 series, including the 600.5's, is in another league sonicly. Better everything, for details take a look at my review of the 350.5 here on the GON. Hope this is helpful to you.
Classe 350 vs Pass Labs X600.5
Would someone compare the classe Cam 350 to the Pass Labs X600.5? I think the CAM 350 runs classe A up to 80 watts and the x600.5 is less. The classe idle watts are 215 for each mono and the Pass Labs is 515 for both? What is the sound like in the midrange and treble? Do they both control the bass the same? Which would you prefer on a difficult speaker like the Eggleston Savoy?
