"> I want an audio link, to send a remote audio source to my home theater
Gee, not as trivial as I though it might be (as you already found). Most of the links seem to be RF. Generally the IR links are mono only (the simple ones, at least).
I assume that you already tried the home theatre magazine advertisments? Bose came up several times but not sure if that is a proprietary link.
Buy a small FM radio transmitter..

May simply do that. Hate to waste it, but I have a 2.4GHz video link, purchased to demo a project... maybe I should just use it ;-)

I think i would hack a TOSLink fiber optic to a "broadcast" version instead. It is digital and handles at least 5.1 already.
The creme de la creme of FM audio links is the synthesized Ramsey Kit and a old 1" Rack tuner. Ramsey tends to have the best bandwidth and low noise, in a pinch I have used it as a link for a outdoor show for
20K people. Audio quality is a lot better then most of the RS/target/walmart FM transmitters, it uses a custom stereo generator chip.Steve Roberts

Wow! Looks nice! Is that legal? Or do I need a low-power license?

depends on the resistor you install in the output stage, as built its part 15 compliant, and puts out a few milliwatts, which is more then enough to saturate a good sized ranch house with say 6" of wire. Its very vswr tolerant, so you can run it into a badly mismatched load without blowing the output stage, and we all know that the antenna and antenna height is what gets you range. put a 50 ohm smd resistor on the output, put it on top of teh stereo and have just the leakage, if your worried, the leakage will be enough :-)

Thanks!

Oh, I took a look around the online catalog, the new one, the FM30 has a dac and a pin diode attenuator to let you set the power to a minimum. Its also about 50$ more.
