I’ve got a large room I use for 2 channel listening and my office. Aside from listening to music I’m also into photography. I have 24x36” prints mounted as well as concert posters I have framed etc. To light all these I installed LED track lights that are controlled by a dimmer.
I have ZERO issues with noise on any of my circuits and can dim the lights with zero buzzing or flickering. The key is you need to buy a good quality dimmer designed for LED. Specifically you want an electronic low voltage dimmer. I bought a Lutron Maestro MAEMLV-600-WH. This is a very expensive dimmer but is the ONLY one I found that didn’t cause an audible hum with the LED track lights I installed. There also doesn’t appear to be any sort of noise on my AC feed to my equipment, whole system sounds great.
