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.

My Krell PB200 is completely silent at full volume and my ear on the grill. If you have noise you could have a ground loop issue, or a source problem. Check you connects, you may find your "noise".

Most amps are typically very quiet with some of the newer "digital" type amps coming up as exceptions. I have had greater problems with preamps or ground loops generating a higher noise floor than anything else. If you have noise within the system ( whatever the source might be ) and you are running very high efficiency speakers ( horns ), the problem will be exagerated to a more noticeable extent.

As to the specifics that you mention Bob, i would start checking tubes. It is possible that it is a noisy design in terms of circuitry, but i would want to rule out a possibly defective tube(s) before placing the blame on the designer / product. Sean
