Radioman; It looks to me that (based on Alex's 1725 watts) you, at the very least, have adequate watt capacity with the outlets you have safety wise. I've done some research on Proac speakers, and the 2.5/3.8s I believe have easy to drive impedence (about 8 Ohm)-- nice speakers BTW. Also, the Rogue monos should not be a difficult load electrically, ie as impedence drops, tube amps do not increase their power demands like a good SS amp does. As Alex notes, I've also read that it's desirable sonically to have the monos on different circuits, but probably all the existing outlets in your room are on the same circuit anyway. BTW, last summer I had an electrician put in 4 Hubbell duplex dedicated outlets and dedicated ground, and it dropped the music's noise floor dramatically, but then required good quality power cords to get rid of brightness (from the stock cheap power cords). Total cost was about $850.-- mostly labor. Good Luck. Craig
