Both Pioneer DV563A (about $179) and Sony DVP-NC685V (about $249) have basic bass management for multi-channel high-res audio. You can set subwoofer on/off, each speaker to large/small, and each speaker volume level. You cannot (on the Sony at least) set speaker distance, aka time arrival. Also these two have fixed crossovers at fairly high frequencies, at 120Hz or higher.
The Pioneer is a multiformat player, inc'l both DVD-A and SACD. The Sony is a DVD and SACD 5-disc changer, but won't do DVD-A.
