Hissing sound coming from tweeters

Right now I'm experiencing a hissing noise coming from the tweeters on my Klipsch RF7II's, and can't figure out what is causing the noise. It's almost like a white noise that is there when the amplifiers are powered on and is not affected by changes in volume.

My system consists of an Oppo BDP-83 blu-ray player, Ayre K-5xe preamp, and two Emotiva UPA-1 mono blocks. My cables are Audioquest King Cobra and Audioquest Emeralds. I would greatly appreciate any help resolving this problem. The hissing sound is very annoying. Thanks.

Yes sir, pay as you go. It wasn't a criticism, it was a suggestions. Sorry if it came off any other way.

No worries Herman, I appreciate the suggestions and didn't take it as criticism. What kind of amps would you recommend to go with highly sensitive speakers? I probably couldn't go wrong with an Ayre power amp to match my pre-amp, but I'm open to other suggestions.

Since you asked......

An SET amp is in my opinion the only amp to pair with them. Bottlehead is a great value if you can solder and follow directions, and you can easily learn to solder. There is a used pair of monoblocks for sale here now (no affiliation)

If it were me I would have put my money in a nice amp first and used a cheap passive pre until I could afford a better preamp. You just might find you really don't need an active preamp.

I was originally using a Marantz 2270 as a pre-amp, but began having some serious problems with it after it was "refurbished". I demoed a couple pre-amps, one was the Ayre K-5xe and the other was an NAD C326BEE. The difference between the two was night and day so I picked up the Ayre on Audiogon (the hi-fi store wanted $2,800 + 9.8% sales tax for a demo model).

I would have to hear the Bottleheads and see if I like them. I have always liked the sound of Mcintosh amps, but they are out of my price range for now.

I would say you are one lucky 25 year old. The Ayre is a great piece to build the system around. I would move slowly. Start by trying to find what other RF7II users are using. There are lots of good, used amps out there from people like Ayre, Bryston, Classe, Edge, Naim, Parasound, Pass Labs, Plinius etc. Power is not the main issue here. Tubes are certainly possible, depending on how much you use the system for home theater and TV. You can probably sell your Emotiva amps pretty easily. Do your research. You have a great base to build on. Take your time. Good luck.
