    My prologue two was left on in error for 3 days. It then started making a loud popping noise and one of the KT88 tubes is flashing (2nd from the right). As soon as it is turned on the same popping noise and flashing starts. What do I do? Is that KT88 blown? Are others blown too?

    • Hi Peter,

      Sorry to see that a tube has “gone”. Those things happen unfortunately. Same as with the tyres of a car. Not often all 4 go at the same time. It depends what is the condition of the tubes to replace just one or all 4. Personally I like the idea of changing tubes once a year and take a memorable date for that. Last day or the first day of the year, birthday or whatever. It gives me the idea that my tubes are not too old. I keep the ones coming out as spare ones in case one of the new ones gives up.

      Sorry I could not respond earlier, but I was hosting my Italian Sonus faber friends who were visiting us for a couple of days. If you have any questions left, please let me know.

    I have just bought a PrimaLuna Prologue Two amply. Now I’m finding a speaker which its price about 500 to 1000 USD (the secondhand).
    Could you show me which model suitable for that price and the PP2 most?
    My listening room is 12m2 (12 metres square) and not have been soundproofed.
    Tannoy Autograph Mini, Tannoy Greenwich is right?
    Thank you very much

    • Dear Tuan,

      A most difficult question as there are so many speakers out there. You mention Tannoy, and for sure these have a good reputation and are no difficult load for a tube amplifier. But there are so many more. But it is impossible to advise from here. The loudspeaker is such a huge combination with the listening room that to get a “best sound” you really have to take advantage of the experience and product collection of your local specialist dealer. At least that’s how we (try to) do it here in The Netherlands. The solution is not always combining the best with another best. It’s your room that sounds (too).

    Hello
    I have recently purchased a Prologue 5 amp and a Prologue 3 preamp. I have been a tube fan for 20 years and have owned many vintage sets. I know there is a MM phono board that can be purchased but I am wondering about my vintage Thorens TD160 with a rega RB301 tonearm and a Blue Point #2 moving coil. Will the MM board you sell work with my turntable setup? Another question I have is on the model 5 amp does not seem to have the softstart working or is there even a soft start on this amp. The softstart works on the #3 preamp just fine. I love the amps and will not sell these amps

    • hermanvandendungen says:

      Sorry, oversaw your comment. I do not know the Blue Point 2 so don’t dare to say Yes or No. The PL5 does not have a softstart as in the PL3. Best regards, Herman

    Hello Herman
    I actually own some speakers celestion 66 studio monitor from february 1977. (vintage!! there were from my father) I had a look at the very nice product range from PrimaLuna and would be interested in the PrimaLuna Prologue Classic. Do you know if it would be a nice combination or if you had experience with this arrangement?

    Thank you very much in advance for your advices
    Best regards
    Jonathan

    • hermanvandendungen says:

      Hi Jonathan,

      Thanks for your email. 1977 I was still a young boy … and to be honest I don’t have any idea about these speakers nor if they cope well with the PrimaLuna ProLogue Classic. I am afraid the only way to find out is finding a PrimaLuna dealer near you and just try it and trust your own ears or maybe find someone having this combination and ask him. Last thing to add is that most speakers perform well with PrimaLuna amps, specially if you are not the “hard-rocking” type of music-lover. Hope you have a chance to enjoy the combination and thank you for being with us on the blog.

        Herman,It just purchased a Prologue premium integrated amp ..I love the sound and build quality! Quick question: I am only using one input (squeezebox to DAC to amp). When I turn the amp on the input defaults to CD. For convenience, I have plugged my DAC into the CD input (so I don’t have to fool with the default input setting).This should not cause any problem or sound quality issues right? Thank you, David

  5. Derek H says:

    Hi

    A question regarding the prologue premium integrated amp. If it is turned off does it remember the last used input and associated volume setting? or does it reset to a default.

    thanks

    • Hi Derek,

      Sorry for delay. I oversaw your question. The answer is reset to default. CD.

        Hi Herman

        I ended up purchasing the Primaluna Premium Integrated with EL34′s. Coming from SS amps, I don’t think I would have made the leap to Valves if your amps didn’t make that process so easy and painless, plus the sound is fantastic too.

        thankyou

        • hermanvandendungen says:

          Hi Derek. Thank You. Thank you for having a PrimaLuna and thank you for pointing out what we are up too. Make it easy and painless to go to tubes from solid state if people want to go that direction. It makes no sense (as we feel and as we see locally here) to bring to market a 50,000 Euro Integrated Tube amplifier because the knobs are pure gold. We want to make the product as reliable as possible as we don’t want you, our dealers, or my tech department have the hassle of repairs. And it is very good to know that -apart from speakers of course- PrimaLuna is the most reliable range of products I have been dealing with dyrung the last 35 years! And I say this with the knowledge that solid state is included in this statement! If a PrimaLuna needs “repair”, it is in 80% of all cases a change of tubes. Easy …. Like changing a wheel of a car …. Although I wonder while I write this how many people still can do that ….

          Enjoy, keep an eye on us and recommend us to your friends :-).

    Hi an alle

    ich habe einen PL Two und bin sehr zufrieden mit dem Gerät….der Klang ist kraftvoll und gleichzeitig zart und differenziert. Dynamik Sprünge werden beeindruckend bewältigt.
    Die Stimmen haben Körper und Ausdruckskraft.
    Was mir aufgefallen ist: Die beiden Röhren 12AX7 leuchten kaum sichtbar???
    Können Sie mir sagen ob dies ein normaler Zustand ist.???

    I have just purchased a DiaLogue Three Preamplifier and would like to know if changing to vintage tubes would make an improvement in sound of stock tubes and if so what are some recomendations both 12u7 and 5ar4

    • hermanvandendungen says:

      Hi Ed,

      Welcome to the world of tubes and changing them. Hard to give a firm advise. Some people claim an improvemen, but also other people swear at the original tubes. I feel the best is to get opinions from other uses on the web and carefully study their answers and decide which (sound)direction you want to go. If you are in the USA, you might also talk to the people from Upscale Audio as they “meet” many more people that are into “tube-rolling” than we are.

    Dear Herman,

    I am not yet own primaluna but considering to purchase Dialog Three and pair of Dialog Seven. I have one questions regarding the connections. Is it possible to have balanced XLR connections ?

    Best Regards,
    Johanes

    • Hi Johanes,

      Sorry I oversaw your reaction. No, PrimaLuna is till today pure single-ended. But who knows what the future will bring? Balanced CAN be an improvement, but isn’t always. Maybe in the meantime enjoy our single-ended products?

      Happy New Year and thanks for your interest.

        Dear Herman,

        Thank you for your suggestions. I agree with you and will visiting local Primaluna dealer within this month. Regarding the tube, is it OK to try this tubes (6550, KT-120) with Dialogue Seven ?

        I also need your suggestions on the Interconnect (from CD Player (I am using Oppo BDP-95) to Preamp and From Preamp to amplififer) and for Speaker Cable. If I am using DHS cable, which type would ypu suggest ? I am considering sonus faber, Sophia 3 (Wilson) or Quad ESL 2905. I understand that the best decisions is after listen them, but at least I would like to start with the correct sequence of auditions.

        Thank you for your suggestions and Wish you successfull with the CES show

        BEst Regards,
        Johanes

        • hermanvandendungen says:

          Physically you can use both 6550 and KT120. We know of people doing it. We have no problems reported. But … the DL7′s are NOT built and specified to be able to handle KT120 tubes. The powersupply is just a very little bit below what is actually specified for use with these tubes.

          As for your other questions: maybe start with something like YTER cables. Neutral.

          Good luck and thanks! Best regards,

        Well, I ended up with the Dialogue One. All I can say is Wow! Here is finally the sound I’ve been hpinog for! After recently upgrading to B&W N805 speakers, my amplification was not enough (125 wpc SS). So, I upgraded to 200 watt SS monoblocks. They control the speakers well, but somehow sound just a bit too antiseptic or electronic. And, just too forward and bright. It seems like the music is being pushed at me. So, I started the trek to find a new amp.I auditioned many amps locally, both SS and tube. Finally, I couldn’t really find what I wanted. Then, they brought out the Dialogue Two. Here was what I was looking for! Sweet, laid back, smooth, just wonderful sound. Vocals sound wonderful, guitars and pianos magical. I have never heard the B&Ws sound better. Ultimately, to save a bit of money, I went with the Dialogue One and upgraded the tubes to KT88. Now that it’s home, I am so impressed and pleased with my system. A few friends have been over to listen to some music, and invariably the sound just makes them smile! Isn’t that what it’s all about? Hearing the music and grinning at least it is for me. Several people told me that tubes don’t work with B&W. To them I say, come check this out. You’ll be astounded. Thanks Kevin Deal and Prima Luna (and of course, my local dealer, Eric and Mark at Audio Perfection) for a wonderful sonic experience! I couldn’t ask for better value! I intend to be a PL customer and advocate for a long time! Steve

    Hello, where can I buy in Spain the Prologue Premium Mono Amplifiers? They Tell Mae that I can only get the Stereo Amplifier. Cheers, Rudi

    • hermanvandendungen says:

      Hi Rudi!

      Very “strange”. WHO is telling you that? All models we produce are available worldwide. At this very moment we stock 3 versions of the ProLogue Premium Power Amp: Stereo, Mono and Stereo/Mono (by switch). What more choice can we give? :-). Ask again please, show this answer and if still not available contact me at herman@durob.nl! Sorry for the inconvenience.

  11. Steve says:

    I’m contemplating purchasing a Dialogue Two. Currently i have a Jolida JD9 phono stage preamp, and I use a Project RM5 with a Sumiko Blue Point #2 cartridge. Would it be better to keep the JD9 as a phono preamp or go with the factory installed unit? Any thoughts on how this would impact sound quality or gain?

    • hermanvandendungen says:

      Sorry, I do not know the JD9 and can only confirm that in general people are surprised about the quality of our small phonoboard.

      • Steve says:

        Thank you for the reply! Do you think your phono stage will match well with the blue point #2? Will it have enough gain?

        • hermanvandendungen says:

    I have setup Phonologue for Primaluna Prologue two. Turntable Rega Planar 3, Cartridge Denon DL-103, Step-up Denon AU-320.
    However, there are some noise (hum) heard while stand near the speaker.
    At Step-up Denon AU-320 there are 2 RCA wire and 1 neutral (mass) wire. But I don’t know how to connect the neutral (mass) wire to stop the noise (hum).
    Would you help me please
    Thank you.

    • hermanvandendungen says:

      Dear TranTuan,

      Normally this installation should be “hum-free”. If you send an email to service@durob.nl Michiel will go through your installation and find out if there is something you can do to get rid off the hum problem.

    Hi Herman

    I have the prologue premium integrated amp. I presume that comes with the silver version of the 12au7 and el34 tubes. Would there be much benefit in moving to the gold version of the 12au7 tubes? Also what is the design differences between the silver and gold versions? Are they made by the same manufacturer, and the manufacturer changed over time.

    Thanks
    Derek

I am bit confuse because, ther are so many models and unable to make my mind. thank you……Donmarcel

    • Dear Donmarcel,

      Wished I could help you from here, but I am absolutely not familiar with the B&W 703 ánd your living room conditions (small, big, damped or not etc). In general I hear B&W being happy with stronger amps, so you might want to look in the DiaLogue range. But please use your own ears under your own conditions at home.

      I recently bought the prologue classic integrated amp with KT88s playing through my fathers old IMF supercompact speakers (also studio reference, from 1974 I think). It sounds fabulous (although it’s my first tube amp and I’m comparing it to the Sony AV receiver I was using previously). I picked up a prologue classic 8 cd player recently also…

    Hi

    I have a primaluna prologue integrated amp.
    Can I connect a pre amp with phono to the integrated amp? My source ia a turntable and I intend to use the phono in the pre amp.
    Will this cause unnecessary damages to both pre and amp?

    Cheers

    • Steve says:

      In my setup I have dialogue one and a separate Jolida tube preamp for the phono. It is connected to aux-in. The two together work wonderfully well. Everyone who listens thinks it sounds great! So, yes you can connect it that way. It would cause a problem if you have the built in phono preamp, though. If you have that use another input not phono.

    • hermanvandendungen says:

      Normally you use a phono preamplifier of which the output goes into the line level input of the PrimaLuna integrated.

    • hermanvandendungen says:

      Mmm.not sure if I understand your question. You want to use an Integrated with phonostage and feed the output to the PrimaLUna. Correct? My first reaction is: that’s a long way.

    What are the best options to (really) improve the 5ar4 that came with the Dialogue 3?
    Is 274b compatible with this machine? Or 5R4GYS (highly regarded on Upscale Audio)?

    I am curious about the Prologue Premium Stereo/Mono power amp. There does not seem to be much information on the internet about this model. Am I right to assume that switching to Mono would give 70wpc in bridged mode? Would this be much difference to just getting the Premium Mono? I am considering to go mono blocks at some stage, but just getting 1 of this model so that I can save up for two and make them monoblocks.

    Hi Herman
    I have set out to try to get the very best sound I can from humble Compact Disks on a limited budget. I bought a pair of second hand, but near new, Magneplanar 1.7 panel speakers. What amazing speakers! I have a Shanling CD-T2000 top loading valve CD payer. Another amazing product. Late last year I bought, after much research, a PrimaLuna Prologue Premium Stereo Power Amp and a PrimaLuna Prologue Premium Stereo Pre Amp. All this is powered through an Isoteck Evo 3 Aquarius power conditioner (another significant improvement) and joined together with high quality Transparent connections and speakers cables. Although the Magnapan speakers are supposed to be hard to drive I am so pleased and delighted with the great sound I am getting.
    The best part is that when the Prologue Premium Stereo Power Amp turned up I was delighted to find that it was actually a Prologue Premium Stereo/Mono power amp. After running the unit for a while i could not resist the temptation and have bought a second Prologue Premium Stereo/Mono power amp so I can run the 2 as mono- blocks which should give an even better sound through the Maggies. There is a reason why i have not tried that as yet. When I ran the first Prologue Premium Stereo/Mono power amp for an extended time (2 – 3 hours) I experienced a problem. There was the occasional sudden full volume burst of sound that could not be turned down with the pre-amp. i had to rush to stop the signal completely. This concerns me. i do not want to damage the speakers or the amp. With the second Prologue Premium Stereo/Mono power amp I have been running it as a stereo amp so that it has a similar running in-time to the first amp. Again the second amp did the same thing as the first when run for an extended time. I have used the Shanling as a preamp and the same problem happened so it is not the Prologue Premium Stereo pre amp as i first thought. The days were warm but the house is air-conditioned and the temperature was around 22 -23 C. I would have thought this was not too hot. I have held off running the 2 amps as mono’s until I understand what the problem with the Prologue Premium Stereo/Mono power amps might be. I am worried about using the higher power of the amps in mono form in case there is another sudden full bust of power that might do some real damage. For the time being I am only running the second amp for about an hour at a time (so I can not use them for background music for now). Do you have any idea what the sudden burst of full power problem is? I should mention in closing how pleased and delighted I am with the sound of my PrimaLuna based system.

    Looking forward to solving the problem and many more hours of enjoyable PrimaLuna music.

      Thanks Kevin for your complete message. Strange. I was thinking direction preamp. But the volume is a standard potmeter. So for max sound it should be turned to max position. Or …. the selector should go to HT Bypas. But thenm this is not possible with use of the Shaling. So I cannot shine any light on this. Sorry about that. Please contact your local dealer. Best regards, Herman

    Hi. I love my Dialogue Premium Integrated. It is the best sound I have ever owned. Playing through Focal 1008BE. heaven.

    As happens to us all I have been tempted into the dark side of tube rolling. I swapped out the 12au7 for Red lions from Upscale Audio. There is now a low level clicking sound coming from the left channel. It doesnt matter which tube is in that spot as I have tried multiple ones. It is independant of the volume control. It goes away if I put back the original Primaluna branded tube. Any idea what may be going on here? Thank you
