If one dared to judge the sound of tube amps solely on the PrimaLuna DiaLogue Six monoblocks one might wonder why the term "tube-y" was coined. Have the designers of the DiaLogue Sixes found a way to eliminate every negative sonic stereotype and accentuate all the positives? Yes, quite possibly.


70 watts ultralinear, 40 watts triode with enough juice to drive most any speaker with ease and grace, and that famous EL-34 warmth people crave. The DiaLogue Six monoblocs begin with the same basic topology as the top-rated DiaLogue One integrated.

But the monoblocks reach a new level of performance using a unique dual-feedback topology: Cross-coupled current feedback for superior impulse behavior and gain stability. Next a slight amount of negative feedback is used to achieve exact gain setting, low distortion, and low output impedance. This effectively cancels the negative byproducts associated with both feedback circuits. The end result utilizes all the benefits of feed-back, without all the drawbacks.

Finally, the monoblocks integrate newly-designed, wide-band, low-loss, output transformers, built to handle even the most difficult speaker loads. Two transformers are wired in parallel in each amp for even greater control and bandwidth. A two Ohm output tap is added for additional flexibility.

Like all PrimaLuna amplifiers, it boasts:

  • Soft-start circuit Extends component and tube life by powering up the amp gently every time you turn it on.
  • Tube plate fuse Protects the amplifier output stage.
  • Adaptive AutoBias. Exclusive to PrimaLuna, this circuit monitors and adjusts bias automatically. Improved performance and better sound, with distortion reduced by 40% to 50% over conventional designs. Plug in virtually any power tube. Adaptive AutoBias will automatically adjust itself! In addition to EL-34s, you can use 6550, KT88, KT90, 6L6GC, KT66, 7581, EL37, and any of their equivalents.
  • Premium parts . Fully vented chassis, chassis-mounted ceramic tube sockets, Alps potentiometer, Nichicon and Realcap capacitors. WBT style speaker terminals. Gold plated input jacks.
  • Hand made with the finest point to point wiring, with workmanship equal to or better than any product you can buy at any price, period.
  • Chassis made of finely finished heavy gauge steel, and five step automotive quality finish. Each coat hand rubbed and polished. Removable tube cage included no charge.
  • Toroidal power transformer for low hum, and a front end that is dead quiet.
  • Conservative design runs tubes easy for long life.

Next we take the DiaLogue Six to new heights with:

  • Triode/Ultralinear switching. Allows you to switch how the power tubes operate on the fly, via a slim aluminum remote, allowing you to stay in your nice comfy seat while switching between the two modes.
  • Improved output transformers designed for wide-bandwidth and high efficiency. These heavy-duty transformers elicit incredible detail from top to bottom, lower the output impedance, and provide the amp with greater control over speakers with difficult loads.

Built to Western standards with PrimaLuna's standard-setting build quality and unparalleled reliability.
