How do you exceed the performance of something that is so close to perfection? The design team in The Netherlands took years to make sure that once again, PrimaLuna would make something that was considered to be not just better, but ground-breaking.
The result has been awe-inspiring with the new DiaLogue Premium. Art Dudley, one of the most famous and well-respected reviewers in the industry, reviewed the DiaLogue Premium power amp as a $3199 stereo amp, not even in the more powerful monoblock mode. He was swift to say "I tried to fiind fault with the PrimaLuna DiaLogue Premium. I failed." He went on to say that he has had the pleasure of reviewing some remarkable amplifiers, and that the DiaLogue Premium "is among the four or five most enjoyable." This is important because Art is the reviewer responsible for some of the most expensive products in the world. Tone Audio Magazine's Jeff Dorgay followed suit, awarding the Product of the Year award.
Word travelled. Martin-Logan, one of the finest loudspeaker manufacturers in the world, asked to use five DiaLogue Premium monoblocks for their incredible surround display at the biggest industry show in America: CEDIA. You have to put your best foot forward at that show. And Martin-Logan has enough clout that virtually any company would die to be in their room. Now, KEF has asked PrimaLuna to provide electronics for their display at AXPONA. Of course we are humbled and thrilled. Now with this success, what more could be done?
It's easy to get more power from a tube. Run it harder. You will see claims of up as high as 100 watts from a pair of KT120's. Initially, the customer is happy. More power is better, right? Well..talk to the same customer in a year. PrimaLuna amps are famous for long tube life, running cool, and being absolutely the easiest amplifier to own. What we've done is increase the power and output transformer size, designed and built a larger Adaptive AutoBias board, and all the supporting circuitry required to run eight power tubes instead of four. Doubling the power and increasing bass slam. Customers can use almost any tube on the market. And their new DiaLogue Premium HP can be shipped with EL-34's, Gold Lion KT88's, or Tung-sol KT120's. You can even use KT150's.

Bought this along with the Dialogue premium pre amplifier and there is no doubt after an initial bedding in period, it has out performed my Icon Audio power amplifiers. The EL84 tubes did not work great with my Tannoy Kensington GR's so I rolled in some KT150's and upgraded the driver tubes to Philips MiniWatt SQ E80CC - which are difficult to get.I find the use of high grade silver interconnects has worked great, along with Van Den Hul Hybrid speaker cable. Build quality is great, and while the remote with the prima luna preamplifier was faulty and had to be replaced, this one was fine.I didn't get great results running in triode mode - ultralinear is clearly much better and more dynamic with the Tannoy speakers.
