Anyone try KT150 in Primaluna Dialogue Premium HP

Yes!  I HIGHLY recommend the KT150s in the Primaluna.  I have the Dialogue HP integrated, and I really liked it with both the stock EL34s and some Tung Sol EL34Bs.  However, my speakers are only 86db sensitivity (Harbeth C7s), so I decided to spring for the KT150s and some NOS Mullards in the preamp section.  The difference was startling. The added power and bass depth was the first thing I noticed, but it's also a surprisingly refined tube.  The midrange is detailed but not harsh at all.  There's a real coherence to the sound from top to bottom.  Of course, the KT150 and Mullard 12au7s are about $1500, so it was a significant investment.  However, as someone else said on a different post about the HP, the KT150s are almost a requirement to get the best out of the amp.

Enjoy!

1" is plenty, and you could probably get away with 3/4" or even 1/2".

I've gotten used to my cage being off, and my kids are old enough now not to touch the tubes.  But your idea to lift it is a good one.

Thank you!  I'm heading to my buddy's place this weekend.  I'll see if he can help me make some sort of 1 inch riser for it.  We will see how it goes!

I'm running KT-120s, not 150's. The 120s fit inside the stock tube cage, no problem.

I wish folk reporting their sonic observations with these amps would also indicate whether they were running triode, or ultralinear. I run mine in triode, and hear no midrange glare. I find ultralinear to be distinctly inferior to my ears, but it's easy to be fooled by its greater output. When I switch from triode to UL, it sounds louder and clearer, but that is just the increase in volume talking. In reality, it is thinner and less rich in tone.

"I wish folk reporting their sonic observations with these amps would also indicate whether they were running triode, or ultralinear."

sqsavior-having heard the HP/150 in a couple of systems, and a fellow owner NOT using them, IMO the KT150 follows what other types do, when switching UL/triode, still has its unique "punch" for lack of a better term.

As mentioned in a different thread, they just give a little "more" of everything. Of course in the end, it ends up being what our own ears find pleasant.

Im not compelled yet, to give the KT150's a spin. My current 2 year old setup of 6L6's still keep me entertained. Looking at bigger gains here, with a leap in a bigger retail  price point in speakers. Current one are nearing 7 years and I think upgrade bug  has bitten. 

I see some owners here have 10k+ boxes with their HP. No doubt the HP easily serves them. My budget is only half, but Ive got a few candidates in mind.
