Has anyone compared K150 tubes and the stock EL34s in Primaluna integrated/amplifiers?


I have a Primaluna Dialogue HP Premium with stock EL34s.  When the EL34s wear out, which I suspect will be a long time, what would I replace them with?  The KT150 is intriguing to me. 

Has anyone compared these tubes, especially in Primaluna gear?  I'm wondering if I would lose the EL34s midrange in exchange for the increased power of KT150s.  It's hard to find, however, a bad review of anyone using KT150s. 

Thanks all!

Yes I tried the 90s when I had my Dialogue PL Premium and did not like them at all.  Felt as if a blanket was over my speakers.  YMMV but felt it was horrible in this amp.  

Resurfacing a six (6) year old thread after a friend asked me a question today. Some old comparisons here - thought I'd give the post a try and see :) Since I don't have any KT77s lying around, only KT120s, KT150s, thought I'd try a post here. Does anyone here feel comfortable remembering back or reporting out by chance -

The ask, for a friend:  

"has anyone on Agon compared a KT150 to a KT77 in their amps before", pros/cons of each, what do you hear comparatively?:
