When I play CD's and set the volume on my Denon above 0, the low end music does not sound right. The detail seems to go out of the bass. I know I said distortion in the title, but I'm not sure if that is technically the right term for the problem I am hearing. Based on what I hear, I suspect it is the speakers 6.5" woofer having a hard time handling the low frequencies at high volume. But, I really don't know. So, is it the speakers or the receiver that is messing the sound up? Receiver: Denon 1802 (80wpc). Speakers: Acoustic Research PS2062 (sensitivity 90db, recommended amp 20-125 watts, Freq Resp 45Hz-20kHz ±3dB). Configuration: Speakers are set to Large (no SW yet). I only occasionally have a desire to play it that loud. I'm hoping its the speakers, and that a sub-woofer will help cure the problem.
