I've got this receiver that a friend was given because he says we both learn and work through issues but I think he brought it over because I know how to get answers and do the work to make it work. I've got it hooked up to a pair of DQ-10s, main rig skip the electronic crossover, extra amp and sub for now, just the speakers. Using FM as I have a decent station to enjoy, XPN.org with new on air folks and all. April is guitar month and they have been playing some tunes featuring good guitar work. Anyway, I'm in the other room and hear a Fleetwood Mac song, World Turning. When the bass drum came in I was startled at how good it sounded. I had to check to see if the tone controls or loudness were on. No tone controls but the loudness was on, still sounded great. Since the unit is mostly background music, loudness is appropriate. I cranked it up to enjoy that. Some of the best bass I have heard from the DQ-10s. Part of the reason the unit has been hooked up for a week and a half...as I get around to setting the bias.
