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?  

What at are your thoughts if you've tried this?  Maybe Kevin Deal has an opinion?

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!
