The Prima Luna Dialogue is a very versatile amp. It allows you to use EL-34's, KT-88's and KT-120's. You also get a choice of triode and ultra-linear modes. W/the auto biasing it's a snap to change tubes. Great build and allows you to configure the sound you like.
Primaluna Prologue vs. Dialogue
Hi guys,
I've just posted this on another forum, so sorry for c/p but I need good info as soon as possible. :)
I've seen a lot of discussion on Primalunas here on Audiogon, so...
I've been looking for a good not so expensive tube amp to use with Tannoy Stirling SE.
I've had the opportunity to try Audio Research VSI75, Leben CS300 and Primaluna Prologue Premium.
AR is on another level, but the price is there too. AR was with KT120 while primaluna is EL34. That for sure makes a big difference, but...
Leben has that magic, but you're limited due to low power even with Stirlings (91dB) - it's ok for acoustic, vocal etc, but play some Pink Floyd and it goes flat.
Then I've tried Primaluna Prologue Premium. For the price it's one of the best amps I've tried. These are the amps I've had at home for longer audition or owned them: Rega Brio-R, Rega Elicir-R, Naim 5si, Musical Fidelity M6si, Accuphase E270, Luxman 505uX and 550AX and now I own Exposure 3010S2D. I've also listened to a lot of other stuff in the shops. Not bragging, just want to give you a perspective.
Now, I'm thinking of selling Expouse and picking up Primaluna. Since I don't like changing amps often, I was wondering should I go for Dialogue?
I've tried searching on the web but there is surprisingly low amount of info from users that have compared Prologue and Dialogue Premium int. Usually it's high praise for either.
I know the specs, but what about the sound? How it differs form Prologue to Dialogue? Is triode mode worth the price difference?
At the moment I'm not interested in Line Magnetic since I can't audition it.
Regards,
Borna

@aniwolfe - thanks! @linnlingo - I'm aware of flexibility regarding tubes, but only noticeable difference from usual specs mentioned is triode/ultra-linear. Nobody other than aniwolfe said anything about sound difference between the two (of all posts I've found so far). I know that specs are better than for Prologue (caps, wiring..) and am afraid that it could impact the sound in a way that it moves it towards "colder" side of things. Prologue is already not overly warm (yeah I know that tube rolling helps :) ) . If it's just the dynamics, than it's a good change. :) |
bornac-the PL distributor@Upscale Audio will give you solid info to your query. i found upgrading from the PL Prologue series to the Dialogue Premium well worth the extra expense. Since you mentioned the ARC VSI75, thus thread may be of interest to you:: https://forum.audiogon.com/discussions/considering-switching-from-audio-research-to-primaluna-troube... A blind comparison of the ARC vs PL Dialogue Premium. |
First , I do not have any experience with the Prologue Premium . I do have experience with a Prologue II Integrated if that would help . It was a nice piece and very versatile with tubes and music . I owned it for about 13 years with flawless operation . I traded it in on a Dialogue Premium Integrated a few years ago . The Dialogue Premium is the Prologue on steroids , for me . The Dialogue does everything that the Prologue did but to a greater extent , just more of everything . Regarding the sound...I found both units sounded like good SS with the stock tubes . Actually , if you want to stick to the EL-34 sound the stock tubes are pretty nice . It is the small tubes that really open up the sound . Especially the four inner tubes , on the Dialogue . I didn't find much of a difference rolling the two driver tubes , the outer ones or first and last from left to right . I left those as stock . I posted a thread about my tube rolling experience some time ago here on the 'gon . As above , I did not find a big difference with the Triode function and prefer to use the U/L function as well . My speakers only have a 92db. efficiency rating so maybe that has something to do with the functionality . I hope that this will help you . Good Luck . |
@tablejockey - thanks! well, that link was some interesting read indeed. :) @saki70 - I've tried tube rolling in prologue and I've noticed a nice difference when changing from EL34 to 6L6 which I took out of some fender guitar amps. Also tried changing driver tubes and it's equally important change. So, to conclude, it's a fine piece of equipment and with tube rolling I'll get it to sound the way I want. I'm chasing one second hand Dialogue Premium. I'll let you know. |
