Thanks for answering for me. I see you all really put some thought on the neighbors from hell problem (remember the PC game?).
You would be amazed on how much low frequency content there is. You start noticing it only when you get something that can reproduce it. Especially with movie effects.
There is only so much you can stress your bass/low mid woofers before they run out of Xmax, a sub can be really useful.
It would be nice if one volumio could play two different signals at the same time.
