I am wondering if anyone can tell me if the onkyo tx-sr601 is enough to power onkyo SKS-HT240 speakers. The receiver is rated at 85 watts per channel and the speakers are rated at 100w. Would the tx-sr701 be a better deal for the extra money? Anyone have any suggestions? In a small apartment would this be sufficient to provide great surround sound? Living room is abut 10ft x 20 ft. Cant be too loud or the neighbors will complain. Thanks in advance...
