I would go with at least 8 dedicated lines.You want to keep every piece of equipment on its own circuit.2 for amps 1 pre amp 1 cd player 1 turntable, 1 self powered sub.you get the picture.Use the hubbels and make sure you use a good power wire.at least 14AWG teflon dialectric with individual shielding and a overall shield.put in a cathedral ceiling if you can.I moved from a 18' long 16' wide by 8' high room to one that is 18'wide 15'long by 10'on one end to 18' on the high end.The difference in sound was incredible.I could have spent 5/10k more in the other room and not achived the same sound upgrade.Dont dampen it to much.Tube traps in the 4 corners and a little on the walls.
New Dedicated Audio Room
I am in the initial stages of buying and building a new home. This home is going to have a dedicated audio room. (Approx 18'x 26') I will be working with the builders regarding the room and want to hear some suggestions regarding sonic improvements. I plan on using Hubbell outlets with 4 dedicated AC lines. I am also going to have the builders use thicker sheet rock for the walls and ceilings. Any other suggestions??
