What are some good tube amps that rock? KT88's?

Hi there, I am currently using an all older CJ SS setup. I fell I need a tube amp to get rid of the grit in my system. I thought upgrading my DAC would do it but it remains.

Its really important to me to be able to play loud, I have been told I would do best with a KT88/6550 based amp. I owned a CJ Premier 11A and loved (Sold it due to budget back in the day). I listen to everything but I play rap,reggae, and rock mostly when I play loud. Im going to be crossing over my speakers at around 60-80HZ

My speakers are B&W Matrix 804's which want a decent amount of current despite their small appearance.

Tanks a million
