Quietest amplifier you have ever owned.

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

I have a different opinion. As I have ML332 amp and use Genghis Khan PC the amp is totally dead quiet. I have tried another power cord to replace the Genghis Khan I can hear the hiss and hum. But I also add a Sound Application with Elrod EPS3 20ampIEC I ain't hear nothing not even closer, absolutely dead quiet.

Maybe you should put some music on. I always feel empty, in an empty room, with an empty cd drawer or naked platter with no musical matter, even more so on an empty stomach. Is listening with no music on a new audiophile preoccupation? And there I was thinking it was about the music! I think this may be the quintessence of audiophilia nervosa, listening to the amp itself without music. The beauty of the s/n ratio in all its nakedness! Heck some people don't even need the amp, they just read the specs on the lew and it fires up their imagination. From my humble but God-awful cold one-holler in the frozen mid-fi trenches, good day!

You're right Pbb. I'm scrapping all my gear and buying Pioneer, Sony, Technics and Kenwood. Think of the money i can save in the future and the money i can put back into my bank account after selling all of the gear that i have now !!! Since the mass market stuff all measures the same, and the measurements are good by most people's standards, and it all produces sound that one "could" call "music", i've wasted a LOT of time, money and effort with the over-priced junk that we call "sound systems". Ha !!! Thanks for opening my eyes !!! You've steered me back onto the right path once again. Both you and Norm Strong have been right all along.... Sean

The Parasound JC-1 is the quietest amp I have owned and it measures 122dB at 400w out into 8r....At 1w out this drops into the upper eighties A-weighted...
