quiet hiss in backround?


i have a quiet hissing from speakers when no music is playing and i am sure it is there when music is on but hard to hear. it drives me crazy! i always attributed it to normal noise from my amplifier but i wonder what you folks think? is it a power issue? the amp is a krell fpb600c, dedicated line, no power conditioning (a small quiet line by audio prism (parallel power line filter) is all. is this normal?

I know the feeling.

Sorry about that!

Audio Research 110 would be a great match and unbeatable at the $'s.

Yes I do think the Krell is a terrible match. Krell would be great with Revels, not Wilson.

Go for it! You won't be dissapointed.
mike i am going to lose my audiogon privileges for asking these questions...i am really not an audiophile, i just love music and great sound. i know some but not much compared to allot of the guys on here...

how much different are tube amps? do they have the same ability i am used to as far as soundstage (it is huge and i suspect allot is the krell), depth, power etc? are they more delicate? how long do tubes last? are you constantly looking for better tubes or do you just use what comes with the amp? am i going to be banned for asking these ?'s?
On those speakers they'll do more than the Krell. They won't be as highly resolving as you're used to. That is what Krell does well. Soundstage should be just as good if not better.

Tubes last a while but if you leave the amp on all the time they'll wear out. You'll probably want an amp that is self biasing which means balance the voltage at the tubes and some track use time. Every once in a while a tube will go out so you might want a good tube tester and a few extras around. I would guess every other year you'll need to change them all out which is nothing more than screwing out the old ones and screwing in the new ones. Yes they require more work than SS but it's not a lot.

My tubes have pins - they aren't threaded.
Thanks for the correction Macrojack. I'm SS these days.

The idea is it's fairly simple. Perhaps you could comment on your experiences?
