Just picked up a used Carver AV-705X amp on ebay. This amp is rated at 5 X 125wpc. Will it be safe to biamp my Paradigm Monitor 7's with this amp? The 7's are rated to handle up to 175w. I will run the center with the 5th channel. My surrounds will be powered by my Pioneer Elite VSX-09TX receiver. Or should I power all 5 channels with this amp? The reason I want to biamp my mains is because I listen to a lot of music with mains and sub in the direct mode. Any help you can give!!
