Well, while they are not Levinson or Krell, I think that the Classe amp you tried, should have provided decent enough bass.
Perhaps changing cables would help.
I changed from Tara Labs Space and Time cables to a MIT 770 CVT, (bi-wired) and I noticed a dramatic increase in bass on my old Sequel IIs, and the bass on my Revels is also good. You could give those a shot.
I hate to say it, but I think it might be your room, in which case that is difficult to correct. I think Rives might be the best person to turn to to solve this problem.
BTW, something I just thought of: What source are you using? I know that some digital (CD) players and quite a few analog sources are weak in their bass response. Perhaps you could try a different source and see if that helps.
Good Luck!
