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!

samzx12,

I'm curious with your opinion concerning GL KT88 vs the KT77. I tried the KT120 and found them a bit glaring. I too, like aniwolfe, am using KT77 with Cifte tubes in my PL Dialogue Premium which sound wonderful. I'm using Cifte in the first 4 slots with the stock PL 12au7 in the last 2 slots. 

Keep us updated with the KT88

Samzx12,

I assume the GL KT88 are fully broken in so what is your opinion vs the GL KT77? Since you indicated the 88s have better controlled bass and top end extension, what about the mid range?
