KT-88 KT-90 KT-100 6550 which has the best bass?

I may get 60 watt 2ch.amp and was wondering which tube will offer the most authority?
I play rock and need the most power and bass I can get out of tubes.
The amp can use all 4 tubes mentioned.
Im leaning towards Svetlana or Electro Harmonix.
Thank you for any info.

It depends how you describe best bass. In my experince with a Graaf tube amp, the 6550 was a warmer more musical sound but the KT-90s were more dynamic and punchier, but lost the magic in the mids. Could be the brand of tubes used also.

Happy Listening
