See, the way I have my setup configured, it doesn't really matter. I was lucky. The room where I have my home theater had a staircase down to the basement behind the wall where the equipment was. I have another staircase going down in another part of the house, plus a bulkhead in from the outside. I really didn't need (or use) this staircase. So I ripped out the stairs and put in a floor, so I ended up with essentially a long closet behind the wall.
I cut a big hole in the wall, and recessed a 60" lcd rear-projection hdtv, which now looks like a flat panel hanging on the wall. All the audio equipment is behind the wall, as is a computer outputting to the hdtv. All the cd and dvd's are archived (cough cough) to hard drives that are in servers in the basement on the complete opposite side of the house. So there really is no noise in the listening room - the pc is essentially in another room! I also have a Gyration RF keyboard/mouse, which have a 30 foot range and can penetrate the wall. So I don't have to be sitting behind a desk to do my computer listening - I can be sitting on my couch, 15 feet away from a large screen. I have a great htpc front-end (
www.xlobby.com) running the dvd and cd library, so simple to use that my wife and child love it.
Now that's the home theater side. For 2 channel music listening, my large Polk SDA's were bannished to another room in the basement, which just wasn't big enough for those baby's to work their imaging magic. So I sold that whole rig, and have moved into the headphone camp
But since I have all the music on servers, I can use my laptop, quiet as can be, in any room of the house and stream the music over the wireless network. I can move the Micro Stack along with the laptop, curl up in a chair, press play on the laptop, and completely forget that a computer is involved.
That's the beauty of this stuff, though. To each his own....
