i've a prima luna prologue 2 using shuguang black treasure kt88z (grade B tubes), sylvania 5751 3 mica black plate and rca clear top. Speakers are proac response d1.
sylvanias and rca clear tops sound more linear and transparent which mix well with the smooth and extremely liquid sounding black treasure kt88z.
Previously i was using sed c wing kt88. It's dynamic with razor sharp focus and pin point imaging but can be quite fatiguing when paired up with the sylvanias and clear tops.
I didnt like sed 6550C or sovtek kt88. Not enough oomph rather flat. They didnt draw out the emotion as much as the sed c wing kt88 or the black treasures.
Other tubes i've tried are full music 12ax7 and create audio 12ax7/12au7.
NOS preamp tubes still sound much better than modern tubes.
My humble opinions....
