Tube Amps With Good Bass Qualities

I have been reading over posts about tube amps and their bass qualities. I understand that for the most part, that a ss amp with have an edge in bass qualities compared to a tubed amp. Damping factor, etc. But I can give up a little of that edge for what I enjoy in the midrange qualities of a tubed amp. So my question is, what tube power amps have you heard that have good bass qualities?  Raven, Quicksilver, Mac, etc.?   Let's give a price point. 5K or under. What do you think?
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.
@georgehifi I didn't see your post just before mine covering the same thing. Hate when that happens. Even improving the source can make the amp and therefore the speakers sound better.

Yes that's for sure also, the main one though is the amp, it has to control the speakers movements, wild and varying loads, high and low impedances, and not be upset by any back emf from the speaker either.

Interesting that there has been no mention of power, power cables, and isolation solutions.
check out - made in Ill - excellent amps, preamps and speakers. Your speakers MUST match your amp though. I have a small 2W/ch Decware amp with 98db speakers. They sound awesome - at least to me.
