Primaluna Dialogue Premium or Premium HP?

I am hoping for some feedback from anyone who has experience with the PL Premium or HP.  I have a Dialogue One now, that I really love!  I have B&W 803N speakers, which are notorious for being hard to drive.  However, this Dialogue drives them wonderfully.  Now, the bug has got me, and I'm thinking to upgrade, to get clearer, cleaner (still tubes) sound, and a bit more power for bass control and power.

That said, I'm considering either the Dialogue Premium or the Dialogue Premium HP integrated amp.  I am able to get a good deal on the HP, making the cost difference unimportant.  Any thoughts on the difference in the two?  Only once, I read that the HP has more power but less finesse.  Anyone have experience with both who could comment on this?  Or other considerations?  Which would you choose if cost weren't the object?  Of course, saying that... going to separates would be cost prohibitive.  I know I'd see even more improvement with separates, but don't want to spend that cash now.

And, there isn't an option for me to audition them next to each other.  I'm going on faith and my current PL experience... and hopefully the collective knowledge of this forum.

Thanks!

Sounderman, congratulations on your acquisition.

As your hearing detects, the sonic upgrade is there, but not in a way which your jaw drops. 
I  found the more you listen, the impression of "upgrade" increases!
RCA black plates along with the same Mazda Cifte's are in my HP. 

You may have to squint your eyes to hear the differences swapping preamp tubes, but a subtle "sparkle" is present with the Cifte. I have also compared the RCA's in the preamp slots.Of course, YMMV.
I personally hear the 6L6G as a nice compromise of the 88 vs 34 sound. The 88 family definitely has more bass, yet the 34's mids just seem more realistic. My REL makes up for any low end missing.

Hi folks

Hope you don't mind me piping in here.  The HP is the exact same amp as the DiaLogue Premium in every way, with these additions:

Larger power transformer, additional circuitry to add four more power tubes including an additional Adaptive AutoBias board, and the headphone amp which I will comment on later.  The benefit is more power and a lower output impedance which will give it a little more slam and control.  Not a ton more.  But more.  So the HP is an all-out attempt to make an integrated that truly will smoke the most expensive separates.   We could have increased power for a cost of maybe $2 by simply raising the plate and screen voltage of the tubes and bias them hard like the rest of the world, but our mission is to try to eliminate tube maintenance by running the tubes at minimum dissipation without going into crossover distortion. 

The 36 watts that the DiaLogue Premium has is huge because we concern ourselves with bandwidth in the output transformers, not power.  As evidenced by John Atkinson's review of the YG Acoustics Carmel 2 loudspeaker where he preferred our amp's bass performance (and sound overall) over 400 watt Parasound Halo monoblocks and $25,000 MBL Coronas.   You can read his comments on the PrimaLuna website. 

The headphone amp of the HP is amongst the best I've ever heard.  As good as my German Malvalve which costs so much more.  In fact better, except if the headphones are super high impedance.  The implementation is unique the way we did it. 

I'm really happy that beyondarkness loves his DiaLogue One so much after so many years.  While other companies certainly want you on the merry go round burning cash, our desire is to create amps that are iconic and relevant 10, 20, or even 50 years from now.  It makes me smile when I get calls from people ten years later that they are still happy. 

Having said that, the new series DiaLogue have the exact same output transformers which is where the magic happens, but with a myriad of improvements that for sure will increase performance.  In a side by side with the same tubes it will become apparent, but I'm going to tell you the original DiaLogue One, Two, ect were so good I thought we had painted ourselves into a corner.

Thanks for your input, Kevin. I actually bought my DiaLogue One from you back in the day. Your post really says it all.

Thank you, Kevin for your input!  I also agree that the Dialogue One I had was a great piece!  I enjoyed it for several years, and decided early on that if I were to upgrade, it would be along the Primaluna path.  I do feel the HP is an improvement in all ways.  I have recently added a pair of Cifte 12AU7s to the input signal path, and this seems to be a match made in heaven.  Even though they aren't yet broken in, we noticed they seem to have the clarity of the Clear Tops with the smooth range of the stock tubes and the bass I was really looking for.  Even the GF said that while she thought it was really good all along, it still seems to get better and better.  To me, that's a truly great testimonial.  

I'm very happy with it, and plan to keep it for many years to come!

I am very close to purchasing a 
Primaluna Dialogue Premium Intergrated amp, but my only hesitation is if it would output enough power for my Martin Logan Adavntage speakers. Does anyone have this combo? Is the 36 watts enough power for electrostats?

Thanks,
