Tube Amps With Good Bass Qualities

Amps don't make good bass.  Speakers create music, including bass response.

While it's true that different designs and different tubes will sound different, if you need more bass you need to find a speaker, compatible with your amp, that will deliver the bass response you are looking for.  With your music, in your room and with your ears.

Manley Labs Mahi Mahi or Snappers with upgraded tubes.  Mahi are a bit quicker with EL-84 tubes.  Snappers are fuller and more powerful with EL-34 tubes.  Tube costs are reasonable for replacement/upgrade and they are quite reliable.

Big party levels? I have thousands of watts available to make noise around my place...from bass amps to QSC pro stuff to a single ended 18 watt Burriss Royal Bluesman...and I can get enough mojo out of my little Dennis Had Firebottle into a pair of Heresy IIIs to shake the paint chips off yer ceiling...if you live outdoors in an abandoned rodeo stadium you may need more horsepower, but if you simply listen to music within 20 feet of my little rig (albeit helped by a couple of powered subs), you're only gonna need a few watts before your head explodes and the disco ball starts spewing mirror chunks...efficiency can't be denied.

Amps don’t make good bass. Speakers create music, including bass response.

Amps control the speakers, especially the bass with damping and current, if not you’ve got crud.

Another vote for Manley amps.  Not always with the same speakers but I've owned several tube amps and believe Manleys are at the top of the list.

Of course that is a generalization.  Some other amp with a particular speaker might be as good or better.  But my point is to try one of the Manley lineup at your particular power and price point before deciding.
