Thanks guys for your replies : )
Yes, I'm looking for mounted bookshelves. Not something to big..
In fact, my main problem right now is how am I going to manage many sources of sounds and 3 set of speakers.
I'm comming from the studio world, and the answer would be: a mixer! I could manage my stuff with channels and all the I/Os...
But in a home setup like mine, what should I use ?
thanks again,
