How does your current system sound at higher volumes?
I think the place I would look next is to pick up some resolution from isolation solutions. We (Audio Asylum Inmates) are about to get a group purchase put together of Barry Diament's Hip Joint roller bearings. I think these would help considerably. You might want to consider some Machina Dynamica isolation base products as well. These are a really effective way to increase resolution. They might not work for you aesthetically or due to vertical space constraints. The roller bearings combined with the platforms yield even more incredible results than either alone. Perhaps some Neuance platforms would be more practical, but I would see what the roller bearings accomplish first.
My guess is that in the end you will probably need to purchase some high efficiency speakers to get to where you desire. There are some good inexpensive options out there.
Given the performance of your home system I know how difficult it is to settle for less. BTW, these isolation suggestions will do wonders for your home system as well.
