I use both the "Furman Power Factor Pro" power conditioner and the "Furman AR-1215" voltage regulator in my rack.
Why would there be issues? These units eliminate issues not create them. I don't use that particular poweramp (I use a 50/50), but I can't see why there would be any problems. In fact my rig never sounded this good until I installed these two units. Now I can rest assured that my rig is getting plenty of clean regulated power without all the line voltage and current variations and noise that come straight from the power company. I highly recommend these units to anyone with a rig they want to protect. Also you'll probably find like I did that power tubes last longer.
