The power cord supplied with the RR2150 performs just fine. If you are going to exercise care anywhere ... exercise care with the interconnects. I was using a silver/copper hybrid interconnect(IXOS Silver Gamma 1001) and it made the sound a bit harsh in the top end. Changing over to Signal Cable Analysis One (copper interconnect) put the sound back in balance. For the rest of the system, I am using Signal Cable Silver Resolution speaker cables; NHT SB2 speakers; and a SONY RDR GX315 DVD player/recorder.
