Prima Luna Dialogue 2 or Cayin A100?


I just returned from CES 2010. I own a pair of Sonus Faber Cremona Auditors and I am looking for a very MUSICAL tube integrated amp. For some time now I have decided on the Cayin A100 (100 watts w/8 KT88) as the SF speakers require power. The Cayin is also reviewed as being very musical with a lush sound stage and is well built. Then I visited Prima Luna and was quite taken by the Dialogue 2. Half the power of the Cayin (PL uses 4 KT88), very well built, auto bias (Cayin isn't) and similar reviews. I listen to jazz of all types, classic rock, blues, and vocals (Holly Cole, Alison Krauss, Krall, etc.). My room is 14 x 26 and I use Acoustic Zen cables. What are the pros/cons of the two amps as you see it? Thank you for your time and feedback.

I had a Prima Luna Prologue Two for one month and then returned it. I loved how it looked and the build quality, but found the high-end harsh, the mids muddled, and everything overly "colored," while my wife disliked the sound even more than me, and disliked having no tone controls.

Had I seen this thread earlier I would have let you know this in advance, as it was only a bot over a week ago that I returned it. My speakers are very clear and revealing, though. I didn't want to bother trying different tubes because I had only one month of use within the return period and I was very busy.

Mine was used and in super-good condition for less than half price, and I got my money back. The shop sold it again the same day. It is a very highly-rated amp with a big cult following, so it must sound great with compatible equipment.

It looked so nice between my black piano, black speakers, and black CD player that it was hard to give-up, even though multiple listenings always returned the same verdict - harsh!
Sorry, I just noticed you got the Dialogue, whereas I had the Prologue. I am surprised, as I had imagined the Dialogue should be steps up above the Prologue, yet from your post maybe not.

My speakers sets are Yamaha NS-1000X, modified B&W 805N in one room, and Rogers LS2a in another. Same Prima Luna sound problems on all. Could be my room set-ups, but I never had the high-end harshness any of with my three previous amps.

I've decided I might just not be a "tube guy," and I'm looking for an SS integrated now.
Saki70 - I also wonder whether there might have been something wrong with the Prima Luna unit I had, such as a faulty component. If so, perhaps Dramapsycho's unit has a similar problem.

My Prima Luna looked so nice, was in minty-new condition, and I bought it for under US$1000, and with all its raving reviews it was hard to return to the shop, but my wife and I both found it unpleasant to listen to and I was too busy to fiddle with blind tube swapping via mail order or room tweaking within the month at-home trial period I had for it.

In retrospect I regret having returned it. At the price I bought it at, I probably should have kept it longer and tried a few things, even taken it to a repair shop for a components check (very expensive here), and then sold it later on eBay or somewhere for a profit later if all tweaks failed to improve the sound.
Good for you, Dramapsycho - It makes me deeply regret having sold my Prima Luna, which I had such a great deal on. The chance of finding one in that condition at that price again in Japan is probably about nill.

As some sort of compensation from the Gods, however, I just upgraded my Ah! Njoe Tjoeb CD player with the upsampler and Siemens 7308 gold pin tubes, and now I am totally happy with the sound of my system, and don't feel I need a new amp anymore, so long as I only play CDs.
