It's not just old style LED's that make noise. When I built my music room last year, I tried out some fixtures that stopped radio reception. God knows what it was doing to the AC line, and I didn't want to know how it was beating against signals in the audio chain.
FWIW, I use only quartz or tungsten lighting (that is, strictly resistive) while listening. The LED's are there strictly for maintenance or when the room is used as a study.
I had good results with Quietrock 545, but it sounds like you're past that stage.
