I realize that this is an older thread but as I found myself today asking the same question as the OP, I thought I should chime in FWIW. I (too) have the DiaLogue P-HP amp (and DiaLogue P-preamp) hooked to Spatial M3 Triode Masters which in combination seem to be a bit lacking in the deep/articulate bass department (with five months of break-in). So I sprung for a set of eight 150s that will arrive this Friday (May 4). I’ll report back on my findings comparing the 150s to the stock EL34s. I had previously tried KT-120s but found them to be too abrasive for my tastes. Hopefully the 150s will bring the bass, retain the mid-range, and avoid the "120 harshness". If not, then I’m off to look at subs.
Anyone try KT150 in Primaluna Dialogue Premium HP
I love my HP. I've had it over a year and have rolled KT120 into it from the EL34. I like both sets. But the EL is more "liquid". The sound is awesome. With the KT120s I like the added power and punch. But it can be a bit fatiguing. It's the midrange glare that I notice most. So I wonder if anyone has rolled KT 150s into it. Does it keep most of the niceness of the EL 34s? Do the 150s have less of that midrange glare?
