Well, bass management on universal players has improved over the last couple years, but it's still a bit unpredictable from player to player. Because of the way the 990's 7.1 direct input works, I'd recommend not even worrying about bass management on a universal player and simply leaving all the speakers set to "large" and the sub to "on" in the player setup. That's what I've done with my Yamaha S1500.
