I run a FURMAN PL-PRO DMC E Power Conditioner in my rack. My 861, HD621 and Oppo all run off it etc and supply clean power to the equipment rack.

Since it has a volt and amp meter my dedicated 20A circuit coming into my room for the rack only (the speakers are all on another 20A dedicated circuit) supplies anywhere between 247-253 Volts and will draw no more than 6amps with all sources on etc so it's getting plenty of clean power etc.

Thanks for all the replies.
