quiet hiss in backround?

I have a suggestion that won't cost you anything more than minimal shipping.

Audition a pair of NuForce Ref9V2 SE amplifiers. They are the quietest amps I have ever heard. You can return them for a refund, less shipping.

If you still have a hiss, then you'll know the problem is elsewhere.

thanks tvad. that amp has won just about every award there is. interesting company and one that i think is going to do very very well. never heard the amp but would like too. quite a value.

Not a suggestion to replace your amp. Just a suggestion to put the amp in your system as a tool to troubleshoot for hiss, as I know it's quiet.

actually, no need to change the amps...if i put my ear to the rear tweeter, i get the same sound just faint. the description earlier in the thread is best, like putting your ear to a sea shell. i am beginning to think it is normal or some sort of power sound in my house. now i am just curious about how much different the 3250 would sound as 2 chan so i am going to switch them anyway. this could push me to let go of the big krell if i get the same punch from a smaller amp...

It's normal.
