As a little note to the -120dB posts, it all depends on how it was calculated. Generally this figure is the difference between output and noise floor. However, at what output? And at what heighth of noise floor? Many ambiguous variables involved and few state the conditions. -120dB is very realizable. Pass quotes -145dB for some of his amps at peak power - quite impressive. Personally, I let me ears to the calculating. Arthur
Quietest amplifier you have ever owned.
I hate it when I'm sitting in the listening chair with no music playing and you can hear the sound of the amplifier coming through the speakers. I was curious what the quietest amps out there might be. One example I can think of would be the Antique Sound Labs MG-SI15DT integrated amplilfier. With the amp on and no music playing I can put my ear right up to the speaker and hear nothing but dead silence. This is probably the quietest amp I have ever had and it probably has something to do with it's single-ended design.
