Can anyone tell me a brand and model of stereo audio swithc 1 INPUT
and 8 OUTPUT for a stereo hi-fi signal, anyone knows if sold on the
web ?

OUTPUT should be possible to select them independently or all
together

Sure. Go to a place like www.markertek.com and search for
"matrix router". Dunno whether the prices for those commercial
units meets your (undisclosed) requirements?
