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!

Timely discussion for me.  I recently purchased a the Dialogue Premium HP Integrated, and I'm thrilled with the sound quality of the stock tubes. It's also the quietest amp I've ever had in my system.  I just ordered the KT150s and NOS 12au7 Mullards.  Can't wait to try them out.  I am running them with Harbeth C7es3 speakers in an all analogue system.

Will let you know how it all sounds once they arrive.

Best, Scott

I just realized that I hadn't followed up.  The KT150s are really amazing.  I have been using them for a few weeks, and I just keep smiling.  They provided both power and finesse with a great soundstage.  Nice bass, and an amazing midrange.  Very coherent from top to bottom.  Highly recommended.

@sqlsavior Good point!  My comparisons were done in ultralinear mode.
