I read in Home Theatre Mag their review on the 700 and it seems to be a sweet sounding piece of equipment. But, under multi-channel loads, the avr loses a lot of juice according to their benchmark test, especially with 7 channels running. It dipped to about 50 watts per channel under 7 channel 8 ohm loads. I was quite surprised at this considering the quality of Anthems amps. Just as a reference, the Marantz 6003 I have under benchmark testing showed as not going below 96 watts under 7 channel loads.
