Thanks, all. I actually do have one 20-amp dedicated outlet near where the amp will be. Currently, I have two powered subwoofers plugged into this outlet (there are four receptacles total). I don't want to have 2-380 watt subwoofer amps and a 450 watt power amp plugged into the same circuit, do I? If I did, I could use a much shorter power cord, but would still need longer unbalanced interconnects.
I redid my electric in 2005, adding 2 dedicated 20 amp lines for my system. I don't have the stomach or the budget for adding any more capacity or dedicated lines.
Elizabeth - I have been told the Pangea has discontinued the 5 meter length, and even that might be cutting it close. I will have to go with either AQ, who offers 20 ft power cords, or one of the custom cable makers, like Signal Cable.
FYI, my preamp is a McIntosh C220 and the amp is an Odyssey Audio HT3.
Please share any thoughts you might have on this.
