I've had a Rogue Cronus Magnum with the EH KT90 to my ears a transparent tube with good definition top to bottom. For me the best new issue KT88 is the Shuguang Black Treasure - dynamic with punch and excellent across the frequency range. Likewise, if you have an amp that takes 6sn7s and the amp allows for swapping in cv181s might want to try the Black Treasures as well. Like the sound of 12au7 , especially the NOS CIFTE Mazda. Have found them more dynamic that NOS Tungsols & Sylvanias that I have. Only tried El34s once, found them lacking beyond the mid-range, prefer the KT88s.
Your thoughts on these different tubes?..
I had tubes in the past from VAC, BAT, CJ and others...but have been in the world of solid state as of late.
Thinking about doing a modest system based on a tube integrated and would appreciate hearing your experience with the following tubes:
Output tubes: KT88 vs 6550C vs EL34 vs KT90
Input/Driver tubes:6922 vs. 12AU7 vs. 12AX7 vs. 6SN7
Thanks for any input...and have good holidays..
