I myself can name just one – Octave Audio V 70 integrated
Which output tubes did the Octave V70 have? The most liquid sounding tubes I had in mine were the EL 34's and original Tung Sol 6550 black or grey plates. The EL 34's did lack the lows. The TS 6550 have much better lows. Ei KT90 type 2 or 3 is also very good. I didn't care for the KT 120's when I upgraded to the V110.
That said Octave has released the V80SE which uses KT 150's. I have heard KT 150's in an AR amps and they sounded extremely good and realistic.
As Pbnaudio mentioned a lot will depend on your speakers. When I had Dyn C1's the TS 6550's were the best sounding. But when I upgraded to Raidho they were too warm and the Ei KT90's were the best.
