Primaluna Dialogue poremium, Rogue Cronus Magnum II or Jolida 801...who can advise me?

Stereo5. 
That's interesting. I guess it really depends on the other equipment it's connected to, and to who's ears are listening! We agree to disagree.....No???

I bought my Prima Luna Dialogue Premium HP integrated from that very same shop in Nashua nh last year, audio video therapy. Great shop and great people. I auditioned the amp and really liked it. 2 things, 1. you can get a prima luna phono stage installed in to one of the aux ins. It’s a card that’s soldered in internally. I have not heard it but it’s reported to be good. I am using a black cube at the moment that is doing the job nicely. 2. The headphone amp is outstanding! It uses all the tubes and is fed off the transformers via a voltage divider circuit like many of the best stand alone headphone amps are. Output is quite high even with my 300ohm headphones. I’ll have to look up the ratings but the output is higher than the new sennheiser hdv820 headphone amp made for their best headphones. The output transformers and design give a huge soundstage and dynamics with quality headphones. I really like the  pl amp a lot

I have a Cayin A-88T Mk.II that is built like a tank and sounds great. It's the same quality as PL and costs a little less. Biasing is easy, all done from the top, no need to move the amp. I use KT-88's and EL34's as well as NOS preamp tubes

I recently did an in shop A/B between the CMII and the PL Prologue (not DiaLogue). For me, the Rogue won hands down, but obviously both have their benefits.

I think personal taste is a huge part of selecting between the two. Some folks criticize the rogue as “clinical” but I’ve found with careful tube rolling that you can maintain Rogue’s detail while getting a warmer sound. 

My my buddy came to the A/B with me and he thought his much cheaper Jolida was on par with the Prologue. Again, not the Dialogue, but that’s what we thought. We aren’t deep experts in this stuff, but we know what we like.

I did buy the Rogue. It’s matched with LS50 speakers, which I think is a decent combo with the right tubes and cabling. Biasing the Rogue is a snap too.
