Hissing sound coming from tweeters

Looks like the amps had been designed with insufficient feedback making them unstable and hiss the tweeters.

Thanks for all the helpful information. I'm at work right now, but when I get home tonight I will disconnect the amps from the pre-amp to determine if this is just a noise floor issue. I understand that the Ayre pre-amp might not pair well with the cheap Emotivas, or maybe the Emotivas have too much gain for my sensitive Klipsch speakers. Once the music is on you dont hear the hiss and it sounds amazing. The hiss is most annoying when you're trying to watch a blu-ray during a quiet scene.

@Herman: In this hobby you can't always afford to buy all the nice gear in one purchase. I just picked up the Ayre and will be looking to upgrade my mono amps in the future. I am 25 years old and my system is a work in progress.

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.
