Tube Amps With Good Bass Qualities

Thank you for the responses. I just went over to the Rogue website and there are a few reviews on that amp. I will have to check them out.  I was not familiar with the Rogue brand. The Atma Sphere S-30 is also something I am not familiar with. At $2500 it is well within the budget.  Much to read! Thank you for all of your responses.

Thank you all for your input, George, Ralph, and everyone else. I've always enjoyed the sound of tube amps, but have found the bass a little "lacking, tubby, soft". But for this shortcoming, tube amps have a sound that I really enjoy. All of these posts have been very informative. I will continue to research and look at the reviews of the suggestions that people have made. I understand that it all comes down to matching an amp with the speakers. I just wanted to get a general idea of what tube amps would deliver acceptable bass. Thanks again for all the input from everyone.
