Ayon Triton is a great suggestion for tube amps with speed and bass.
There are many others but typically tube amps which try to do too well in bass lacks the magic in the mids and highs. Many examples exist. So you probably need to find a good tube which can drive your speakers in a reasonably sized room. Bass speed is the criteria to look for, not exactly how low it goes. 60 watts push-pull should be a good starting point.
