Denon 2900 via analog (sacd only) to Denon 5803 sent to Paradigm 100 mains, cc570 center, servo 15 sub (superbly accurate bass...and lots of it...yeah) and monitor surrounds (less than ideal...I know, but the timbre is not so far off). Sub level set to 0 and all others at -10.
You've made this into a bass management issue (a non-issue with full range speakers) and a level matching issue, which I firmly believe can be done with a well tuned ear. After all, that's what we ultimately use, is it not? While the 2900 lacks in a couple of areas (time alignment), I am profoundly impressed with its sacd capability and playback on my system. The biggest improvement I could make for sacd playback would be studio rears, but believe me, it's not that lacking. What I hold in high regard for good sacd playback is phenomenal speakers and good speaker placement.
