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

See parsons comments on this thread. https://forum.audiogon.com/discussions/considering-switching-from-audio-research-to-primaluna-troube...

In my opinion, everyone commenting about sound quality on a dual-mode amp like the PrimaLuna Dialogue Premium should indicate whether their observations apply to ultralinear mode, or triode mode, or both, if that is the case.

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

I've only run in ultralinear with KT150.  Have Revel Ultima Salon 2, and have a VTL TL 7.5ii pre using 12AU7 tubes I like for their neutrality (I think they are PSVANE - essentially sorted out chinese tubes).

Sounds is very fine, and I have not felt the need to tweak.  They warm up and we are off to the races with sweet (but not drippy rich) tonality from bass to treble, definition with out etch, dynamics (maybe a bit wobbly on bass if its hit hard, but with a musicality that covers the loss of ultimate control).  Love the sound.

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?
