Las Vegas 2011 (3)

Finally the show opens its doors.

At 9.30 am we were all there -except Herman who was doing The Show- in our Sunday clothes. Music had been on all night and we only had to turn up the volume a bit.


Big queues at the lifts and finally the crowd started to fill in the different rows. Within one hour it was already quite difficult to enter our rooms. Jill is at the doors trying to organize the flow; Cy and Jared are caring for the American reps; Kevin is busy with the American press; Dominique is responsible of the international guests (distributors and press). Herman is at The Show and returned at 14.00 for the first meetings.

The demos start and reactions are really positive.

Dick Olsher, Ken Kessler, Paul Miller are coming in respectively for private listenings. The Japanese, Turkish press also get in and we inform them about the new developements.

Herman and Paul Miller (HiFi-News)

Ken Kessler “at rest” 

The open products attract the attention. The picture underneath is the PrimaLuna ProLogue Premium preamplifier.

Now the PrimaLuna Prologue Premium Integrated Amplifier:

And the Mystere Integrated Amplifier:

We are also showing for the first time a protype of the new DiaLogue Premium Integrated Amplifier

The DiaLogue Premium Integrated Amplifier is the first to go with 3 x 12AU7 tubes. So the full machine has 10 tubes! Less nois, less thd, more tube sound. And of course the more tubes, the better looks :-). More tomorrow, it is ” Enjoy your meal” time!

    Dear Herman, Dominique,

    Today is the last day of the CES, we sincerely hope that you both had the time of your life at the CES 2011 and that you both will be happy to get back home in one piece after so much hard work in Vegas.
    From this side of the planet I want to thank you both for the tremendous work and for the fact that Herman was capable of giving me (and probably others too ) the feeling that we where “there” with you.

    “Less noise – less THD more tube sound and better looks” 😉

    Keep-up the good work and don’t forget to enjoy the show!

    All the best and have a nice trip back home, I’ll be all ears when you’re back 🙂

    Warm regards,

    José (you know who)

    • Hi José,

      Thanks for the mesage :-). The work is not that hard, it is just a matter of a being in time in the morning. Full day we meet people who are happy about what we did and do, so that’s easy. Lot’s of attention for PrimaLuna, Mystère and unbelievable positive reactions about The Return of Kiseki!

    I take pleasure reading your information. I notice the picture of a protoype amplifier, Premium Dialogue Integrated amplifier. Can you tell me more already about this? I live in Ukraine and it is very difficult to get information here, as well as product. I own a ProLogue Two and am very happy with it, but maybe one day I want to update to something else within your family of products. Thank you very much. Sasha

    • Hi Sasha,

      Thank you for your comment and owning one of our products. I can understand that things are a bit more difficult in Ukraine as elsewhere, but if needed you can always come back to us for info or technical assistance.

      As for your mentioning of DiaLogue Premium Integrated Amplifier, this is an early, or better, the first prototype (or should I say “study-model”) of what we hope to introduce later on as a new future product. We don’t even have a sample of this in our design department yet. Like any other manufacturer (at least that is what we hope) we have continuous development of our range of products. We follow the rule that we constantly try to improve on what we have, so basically I can say we work all the time on our “basic” design. We experiment with different parts, different lay outs to see and hear what is the effect of that. Sometimes we go a bit further and make a bigger change. Like we did when we introduced the 2 x 12AU7 per channel in the ProLogue Premium range. That gave us sufficient reason to further experiment with that and somewhere last year we even went further and started experimenting with 3 x 12AU7 per channel. This was done “outboard” as we had no chassis available anyway with all the holes needed to place this new number of tubes. So we decided to order a first study model with a more reliable construction of this new idea (so we have a chassis in which all the tubes we want to use, do indeed fit) as that will make further experimenting a lot easier. As that first study model was ready just before CES I decided it was nice to have it in the CES room. Just to show, not to demo. It still has to be connected for the first time! Of course it has been connected and checked in the factory! We do hope to receive that sample (and another 230V version) within a few weeks and will start listening to it in The Netherlands. Next to that we will continue our promising experiments with different ac fuses as we did on other models. We have just received several different brands of high quality resistors which we will install in this study model (and other models) to see what’s the effect on the sonic results. We will also start experimenting with different tubes. The usual thing you have to do all the time as a designer, manufacturer and sometimes as a hobbyist if you are qualified in electronics and have the time for it. And then …. one day, when I (and only I) decide the time has come to stop for a moment the developments, I try to come to an agreement with a number of people in my direct environment that I trust very much (consumers, dealers, recviers included) that it is worthwhile to bring this new version to the general public as a final product. After that decision and after having entered the order we start collecting metalwork, parts etc. Three or 4 months later first real products become available. First in Europe as we want to be “near” if a change has to be made for whatever reason and after that in the rest of the world. I describe this process as not everyone is aware of that and because clients outside The Netherlands cannot really be included in this process, simply due for distance reasons.

      I hope you don’t mind I gave you such a long answer, but that sometimes happens while typing about new developments. 🙂

      Best regards and maybe one day we can discuss the final product that came out of this study model.

      Herman van den Dungen
