Does anyone have suggestions for tube rolling on the Spirit II amp? I have harshness on piano transients and some clarinet passages that is just grating. I replaced the original RCA 12AU7's with a different set of RCA's that were supposed to be smoother... and it helped some... but not enough. The Gold Lion KT88's --- perhaps some of you have replaced them with different KT88's or perhaps 6550's or KT120's --- if so how sonically do things change?
Has anyone else had this harshness and if so, how did you get rid of it?
