Heathen has most of the bass in the .1 channel. As such, a normal "small sats + sub" set up will sound fine. In fact, Heathen is quite bass heavy, putting aside where the bass is mixed.
However, if there are BM problems in a player, a disc with a lot of the bass in the main channels and little in the .1 (the DVD-A of Hotel California, title track, for example) will sound very weak.
FTR, HC has great bass and kick drum on the title cut. If you are not hearing that, something ain't right.
Based on Brajesh's experience, as well as a few other reports, there seems to be something not quite right with the BM in the 563.
I don't have one, but recommended it to a friend, and she bought it. If this thing lacks BM on SACD and DVD-A, that is going to suck.
Someone with some additional software (Chesky stuff mixed in 4.0 for example) is going to need to do some more scientific testing to understand what this thing does, and what it does not do.
Needing a $250 ICBM for a $178 player is NOT going to go over well. Cripes, I was pissed to have to do it for my $480 (at the time) 45A.
