The V12i I own performs nicely in triode. I was interested in the Six Packs at one time, but since I got a real good deal on a pre-owned V12i I went in that direction. I have played with two-thirds triode and the sound is a little less sweeter than triode, but much better than ultra linear, which I thought had the oomph, but not much more. A little flat actually.
As for tubes, I could not stomach KT-88s in the V12i. I am now using Siemens NOS EL-34s from the 70's. What a difference. Greatly improved the sound, especially in the bass. Much cleaner.
