I would say make sure you have quality AC lines/and recepticles ( plugs ) coming in..Most will start from the electrical panel in, and provide at least 3 Dedicated ac lines..This would be where I would start ( if you haven't already ) and what ever money you have left, spend on something else..If you don't have quality AC coming in, all the after thoughts could be wasted....Hope that makes sense.
Improve my system
I got the mod bug recently but don't know where to make my next upgrade. Right now i'm running a Yamaha DSP-A1 along with the BK ref 200.5 amp. My speakers are Kef Q70's for front surrounds, Energy APS5-2 for mains, Kef 200c for center, Kef Q70's for rears. Energy microstar 12.1 for subwoofer. I'm using a sony PS3 for my bluray player. I got about 2k to spend on a new toy. What should i spend it on?
