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
