Class D Amps - FM reception

Are there any high quality Class D (or equivalent) amps that do not interfere with FM reception. (I read that NuForce amps, for example, destroy FM reception.)I would like to try one out in my bedroom system but I listen to FM a lot in that room and don't want to lose my recetion. Thanks.

Thanks, all. Sounds like a headache I can avoid with a traditional SS amp. Perhaps next generation of Class D amps will solve this problem.

The Nuforce is the only brand I recall as having the reported noise problem as well as turn on noise and the no-load vulnerability. These strike me as implementation issues and not reflective of class D amps in general.

It may be that only the Nuforce models have FM noise problems to solve.

I just received my H20 Stereo 250 Sig back with an upgrade to the newest version ICE modules and V-Caps ugrades. I am presently breaking it in with a JVC FM tuner and have absolutely no problems with FM interference.

I have my vintage tuner sitting right besides (6 inches away) two Bel Canto S-300 amplifiers and have had no trouble with FM interference. I am using a small passive FM antenna located about 1 foot above the tuner.

Nuforce is having success eliminating the RFI FM interference in newer versions of their amps, as I understand (and have seen demonstrated).
