I like the bass heavy sound of my Pioneer SX838 in my unfinished basement/garage. But upstairs, with carpeting and upholstered furnishings, I prefer the "natural sound" of my Yamaha CR620. I've had more powerful Yamahas up there....CR2020, M4, M45. They all sounded great but I tended to expect too much from them and was often disappointed as they went into protection with too much volume (except the 2020 never shut down...just sounded clean but I was afraid to turn it up past 1:00 as it was such a lovely and valuable piece. I sold it to a friend who cranks it and loves it dearly) With the 620, there's plenty of bass and it punches quick and tight. I like that. Mids and highs feel accurate and true to my ears. I don't feel the urge to overdrive it and am perfectly content....for now.
