Primaluna amplifier Prologue vs Dialogue Anyone heard both? Worth it?

Read reviews and call Upscale Audio.  I'm sure Kevin or one of their staff will be able to answer your questions.  Also their website will plenty of information on each.  I have Dialogue Premium integrated and it's the best my system has ever sounded.  

I have owned the PL1, the PL3&5 combo, as well as the Dialogue 1 and the Dialogue 2. I sold off the Prologues a couple of years ago. The Dialogue 1 and 2 are both much better than the Prologue units. Better bass/lower midrange for one thing. I presently use the Dialogue 2 with Tong Sol 6550's and the Dialogue 1 with SED KT88's. The latter match is my favorite of the two. FWIW.

BTW, price wise, the Dialogue Two s 'are  showing up for 1600 and less. I haven't seen many Ones come up though. 

yes, im decided to go with dialogue. Now I'm trying to between the Dialogue Two, Dialogue Premium or Dialogue Premium HP.
anyone?

I have not listened to the 'Premium' units, but from what I hear they will be more linear and modern sounding than the earlier Dialogues. If that is so then they might loose a bit of the warmth of the earlier Dialogues. I would miss that. Another personal reservation I have is that the small tube selection will be limited to 12AU7's  What little changes I have made in my amps have been based on selection of 12AX7's , a type I have used for many years and have knowledge of how they will change the tone. Not so much with the 12AU7's. 

FWIW.
