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!

Have tried quite a few tubes in the HP Dia prem.

The other nice sounding tube if you like the warmth of the EL34 is the re-issue Mullard KT88s.

great midrange on that tube.

would also suggest the EL 6CA7 Fat bottle. very musical sounding tube.

have also tried the Tungsol 6550 and KT-120s. Both are a great match for the amp, and sound extended on the top and bottom but do not have the midrange of the Mullard '88s or the EL34s.

the other tube not to forget is the first input tube, 12au7. Rolling in a NOS Mullard or other desired choice has a large effect on tonal qualities.
