Correction: The Pass 600 idles at 600 watts giving it 150 watts of Class A. I used them on 4 ohm Apogee speakers without budging past the idle current flow even at high decibles. I'm using it on the 1 ohm Apogee Scintilla now, and at moderately loud volume, it still doesn't move beyond class A. When I crank it way up, yes it does move to B on heavy transients, and I don't detect a difference, the amp runs so clean.
Class A amplifier choice, need suggestions
What is your favorite class A amp and why? There are many here on Audiogon... Levinson, Krell, Pass Labs, Plinius and an occaisional Accuphase A50V. I am driving Proac Response 3.8s (88dB efficiency). I recently auditioned a Pass Aleph 5 and was stunned by the presentation at only 60wpc.
