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.

Your input is much appreciated!

Hello,

I currently own an PS Audio HCA-2, which is one of the cheapest class A rated amps (by Stereophile) in the world. The sound is awesome... very fast and tight bass, transparent and grainless trebles, female voice sounds exceptionally good. I had it run for 5 straight days and the amp wasn't even warm when touched. Since I don't have a dedicated circuit, the amp's 95% power efficiency really help. When I first had the amp, I did experience ground loop hum. After I lifted the ground (by removing the ground wire from my PC), everything went silent. This amp is driving the Tyler Acoustics Linbrooks with outboard crossovers by the way.
Disclaimer: I am in no way associated with PS Audio or a dealer. I am just a very happy audiophile who bought an outstanding product at an affordable price.

Good luck with your search for the perfect amp!
