Primaluna Dialogue Premium power amp vs. Dialogue Premium HP power amp?


Has anyone gone from the Primaluna Dialogue Premium power amp to the Dialogue Premium HP power amp? And if so, what were your impressions of such a move? I currently have the DL Premium power amp running  KT150s.

I have the PL HP integrated, not the amp.

From what I understand, it's pretty much the same underneath the hood, with the exception of 4 more power tubes.  Probably a subjective difference, other than obvious headroom when you  turn the volume knob.

I would like to try the KT 150, but 8@ $100 each, a bit steep. I use some old 50's 6L6's.
Thank you for the feedback. I bet the vintage 6L6's sound good. I like to run the amp in triode mode often and the 150s are great for that. Thanks again tablejockey.
