Primaluna Dialogue Premium HP Driving PSB Imagine T2s

All--

I have my eye on a Primaluna Dialogue Premium HP to drive my PSB Imagine T2s.   I heard the Primaluna Dialogue driving KEF R700s last week, and I loved the sound in the showroom.  

My current system is the following: 
Creek Evolution 100 A integrated amplifier
Bluesound Node 2, streaming tidal to Creek Ruby DAC
Roksan Radius V with Ortofon 2M Black MM cartridge

My short term plan would be to use the Creek Evolution (or my Creek 5350SE with passive preamp) as the preamplifier.  

I would think the Dialogue Premium HP amp would have no trouble driving the PSB Imagine T2s in a 13' x 21' room (with the loudspeakers placed along the shorter wall of the rectangle room.   

Thoughts?  Appreciate all responses.  You folks have just been great in providing insight and help.

Have you asked Upscale Audio or Kevin Deal as he is the US importer of Primaluna and quite the expert? What is the efficiency of your PSB’s?

I'm pushing Tyler Acoustics Highland series of speakers with my Primaluna Dialogue integrated with no issues at all. They are 89db and I have used a variety of power tubes (EL34, KT77, KT88, KT120 and now KT150). None of the tubes ever strained but the 150's have really opened up the sound. Not as warm or syrupy as the EL34's but the soundstage is quite a bit larger with more punch. The EH KT88 and TS KT120 were my least favorite as they both for my tastes had too much midrange glare or energy. The new issue Mullard EL34 sounded glorious as does the Gold Lion KT77 however, the overall dynamics and soundstaging goes to the KT150.

Yes to retube your HP to KT150 is expensive and only you can decide whether its worth it. Keep your eyes out for gently used to tubes which may help the billfold lol. I will eventually roll back in my other power tubes as it is fun to experiment with different combinations. The stock tubes aren't bad but as usual we like to wonder if there is better out there. The EL34 and KT77 seem to have more midbass than the KT150 but the 150's are more dynamic and the soundstage is larger. They only have about 30 hours so I am hoping they get better and better. Not sure how long it takes for power tubes to actually start sounding their best?
