When a replacement for the awe-inspiring DiaLogue One and DiaLogue Two integrated amplifiers were being penned by the PrimaLuna engineers in The Netherlands, it was a difficult job ahead. They had to exceed the performance of two products that were some of the best reviewed in the industry. Both models had won more accolades and awards than they surely could have hoped for. It was a challenge that the Dutch team took to heart.

The result has been an explosion that could never be predicted. Immediately, there was a rave review Stereophile's Sam Tellig resulting in a Stereophile Class A rating, which means "the best without regard to cost". A review from The Absolute Sound's Dick Olsher ended by saying "It is my current benchmark in integrated tube amplifiers." The Absolute Sound followed up by awarding a 2014 Editor's Choice Award. But it was the buzz generated by audiophiles around the world that propelled the DiaLogue Premium to a position of the being the one you want to own.

 

  • Adaptive AutoBias. A PrimaLuna exclusive. If anybody tells you that they have auto bias, ask them precisely how.  It's most likely not true.  As with all PrimaLuna amps, you never have to worry about biasing your amp ever again, and the need for matched tubes is eliminated.  Just plug in EL34, KT88, or KT120 (as well as many others) and AAB does the rest while improving sound quality.  Tubes are constantly monitored and kept in their best operating range, reducing distortion by up to 50%!
  • Point to point wired with Swiss made cable It's obvious that point to point wiring sounds better and lasts longer than wave-soldered thin printed circuit boards. It's what sets PrimaLuna apart and is part of our credo. In the new DiaLogue Premium we went a step further by using Swiss-made, silver-plated, oxygen-free continuous crystal (OCC) copper with a Teflon dielectric in the critical signal path for superior signal speed and increased clarity.
  • ALPS Blue Velvet motorized volume control tracks better so a defined stereo image is established and doesn't collapse as you raise and lower volume. And it will stay quiet, adhering to PrimaLuna's guiding principle of "Built to last a lifetime". This part alone costs ten times more than a simple "chip" that we could have used.
  • TAKMAN Resistors.If you wanted to push the performance envelope with your existing gear, you would pay hudreds to make this upgrade. Easy to identify through there pink color, these premium resistors made in Japan are popular with those who rebuild and upgrade there gear. "Modders" love TAKMAN for their low noise, linearity, and musicality.
  • SCR Tinfoil Caps. Made in France, these capacitors are used in the critical signal paths and while they are expensive, the PrimaLuna team they could not be left out after careful listening comparisons with many different types.
  • AC Offset Killer. A PrimaLuna exclusive. This is another PrimaLuna "magic bullet" design to make our products so quiet, you will get goose-bumps. PrimaLuna's parent company Durob Audio B.V. sells this as a stand alone item under the Ah! brand name. The fabulous company P.S. Audio sold something similar as a "Humbuster". It's job is to keep the main AC power transformer as quiet as possible. PrimaLuna custom-winds a superb AC toroidal transformers that are low in hum. This circuit takes it a to a place no other manufacturer dreams of going. Adding this to your stereo would cost hundreds.
  • SuperQuiet Line Inputs. Selector switches mounted on the front panel have two problems: First, there are often long wires that run from the switch in the front to the rear RCA jacks, and they invite stray noise like RF and EMI. Second, switches don't make the best contact when new, and the quality degrades as the switch gets dirty and worn. Then, selector switches have crosstalk between the inputs. You've probably heard it yourself; you're listening to a CD and the music ends, and you can hear a faint signal from your tuner. Or a slight hiss, hum, or buzz coming in to through inputs you aren't using. The noise can be obvious, or so small that you can't really identify it. The negative effect is the same: It obscures micro details in the music that allow you to make out things like the body of a guitar or the sense of space in a hall.
  • PrimaLuna has a better way. Instead of a switch, input selection is done using premium quality sealed relays made by Fujitsu in Japan, mounted in the rear where you plug in your components. When an input is selected, that relay closes giving you the best connection possible. All the other relays are left open, so noise and signals from other sources can't leak in. Relays open and close, so there is no wiper to get dirty, noisy, or wear out. The signal path is much shorter. In fact it's almost non-existent, so there are no long wires to pick up noise.
  • New front-end circuitry. The DiaLogue Premium Integrated uses three 12AU7 tubes per channel. The result is even lower distortion and increased bandwidth. The change in dynamic range is stunning! Distortion levels in the first stage have dropped by a factor of five at low levels, and at least 20 at higher levels, above one volt. The four 12AU7's on the outside are driver tubes. By using four instead of two, we can swing more voltage. The two tubes in the center are the input tubes, and that's where you want to have fun later if you wish by experimenting with different tube brands.
  • Triode/Ultralinear switching. In ultralinear, the sound is just that.  Ultra-linear.  The flattest response.  In triode mode you get the sound that people would compare to 300B single-ended amps.  A warmer, more liquid presentation.  Which is better?  There is no answer.  It depends on your tastes, the speakers, and what you are listening to.  It's up to you.  The best part is, that unlike other brands, you can change on the fly from your listening position with the remote control and you don't have to turn off the amp to do it!
  • Dedicated subwoofer output. If you're favorite sub only uses line-level inputs, such as the JL Audio subwoofers, the DiaLogue Premium Integrated makes it simple to use!
