I've done a fair amount of research on updating my AV setup, and creating a new audio listening room. Was wondering if I could get your opinions on some questions I'm working through.

I have a roughly L-shaped basement with the AV area at one end (that is darker), and a sitting area (for listening to music)

AV area (14'x18'): Will be updating my AV receiver and Blue Ray player. Something like Pioneer SC-1222-K or Denon 3313... Running some older Klipsch KSB speakers and subwoofer which I think sound great. Apple TV.

Audio area (14'x23'): Favoring Magnepan MMG. All music streamed from my computer.

Here's what I'm working through:

1) OK to wire in wall ~60-70' (up and down the walls and across the room and from speaker jack to speaker) 12 gauge from MMGs to the AV receiver? Less equipment and room clutter is an advantage. I would either stream music wireless to the Apple TV to the receiver, or if that proved suboptimal or unreliable, install a dedicated computer (Mac mini) to wire to the receiver.

2) Or will I be that much better served with dedicated preamp DAC+amp in the listening room? Such as the Emotiva XDA-2 + Emotiva XPA-200. Gives some flexibility to add a subwoofer, although I'm not really into overwhelming bass for music so see that as remote.

I am not a serious audiophile (at this point) but will appreciate quality sound. Do not listen to music too loud.

Thanks for any opinions, advice, and help.
