I accidentally responded to the wrong thread, so I'll give my $0.02 on this.
It is really surprising the general lack of bass management on stereo equipment. One product I found interesting is the Emotiva USP-1 pre/pro.
It is pretty expensive and totally overkill for OP's setup, but I'm sure its well worth it depending on your gear.
I was generally surprised about the cost of multi-channel receivers being pretty low compared to a lot of the stereo gear out there and they offer much better bass management.
The OP may want to check out the miniDSP, it is fairly affordable and could be a fun way to get some good bass management results.
