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.

I went thru the 'tube flipping' phase several years ago. In a c-j premier 11, I replaced the 6550 with a quad of the the kt90 series. Yes, I had some extended bass, but lost some sound stage. I really recommend using the tubes recommended by the manufacture of the equipment. The sound will be different, but not necessarly better!
