My Stage had a lot of great bass matched with a tube amp. One shouldn't feel nervous about an Apogee. The Stage does not need a brute amp to sound great. It is more important to have a clean sounding amp that is at least moderately strong. You don't need to spend the bank, either. If you want it all, then look into the ICE amps. There is no more powerful amp, that I have heard of, than the ICE amps mentioned above. The H2O shares the best sonic attributes of tube gear, with the muscle of the biggest Krell.
