Nunki - I found the same with the KT120's except mine that came with my new Octave V110 and after 25 hrs they really changed. I mean they got very tight in the lows - the mids got very forward and the highs got a tad bright. I too switched back to the Ei KT90's and loaned the KT120's to a friend with a V80 and he put about 100 hrs on them. I tried them again for about another 50 hrs and they seemed a bit more balanced (not enough for me) from lows to highs but for me the Ei KT90's just blow the 120's away. To me the KT120 is a punchier and more gutsy sound but not balanced from top to bottom. It's all personal taste.
That said the original Tung Sol 6550 black plates blow the Ei KT90's away. Also since my V110 is designed to take advantage of the extra power of the KT120's (higher plate and grid voltage which is switch selectable between 70W and 110W) I found the Ei KT90's can also be run at the higher power setting which to me sounds better (tried both power settings).
As far as extra power I wrote to Dynaudio (distributor of Octave) who in turn wrote to Andreas Hoffman at Octave (owner and designer) regarding the use of KT150's in my V110. The response back was that Andreas is very impressed with the KT150 sound and he did test them in the V110 stating they will work just fine. But he said there is no power gain by dropping in the KT150's (without a circuit re-design) but also said I would only be hearing the sonic differences between the KT120 and KT150. He also hinted at possibly redesigning the V80 to take full advantage of the KT150.
