DiaLogue Series

PrimaLuna’s recently released DiaLogue Series picks up where the critically-acclaimed ProLogue Series left off. For those of you who may have been shipwrecked or perhaps incarcerated for the last three years, the PrimaLuna ProLogue Series of tube components has been embraced by the audio world like no other product in recent memory. Capturing some of the industry’s most coveted awards (Product of the Year, Editor’s Choice, Golden Ear, Recommended Component, etc.), critics and audiophiles around the world have praised ProLogue’s sound, construction, value and dependability. DiaLogue – the step-up line – currently has two integrated amps out, and they are smokin’!

Start with the DiaLogues’ transformers. The DiaLogue integrateds tip the scales at nearly 70 pounds! That’s about twice as heavy as their ProLogue cousins and most of that weight is found in the iron – the heart of any tube amp. PrimaLuna’s global team spent years designing DiaLogue’s high-performance power and output transformers and the result is the purest power you can imagine. DiaLogue will easily drive difficult speaker loads and satisfy the demands of any music from Mozart to Metallica with incredible compression, broarder bandwidth, and increased headroom.

Now add a gorgeous, ergonomically-correct, brushed aluminum remote that allows you not only to control volume and source selection, but also to engage DiaLogue’s home theater pass-thru and to switch the amp’s output from triode to ultralinear all without leaving the comfort of your La-Z-Boy.

All this is added to the standard features that made the ProLogue pieces famous:

Point-to-point wiring

Soft-Start circuitry and an advanced, conservative design (for extendend life of critical components)

Premium parts such as ceramic tube sockets, ALPS volume control, Nichicon and Realcap capacitors and WBT-style speaker terminals

Adaptive AutoBias™ (PrimaLuna exclusive), a circuit that constantly reads each tube and as the demand on the tube changes, instantly adjusts bias, bringing the tube back to its sweetspot. Adaptive AutoBias also allows you to use a wide assortment of power tubes, and you never have to make any adjustments or bias tubes – EVER!

Of course, the whole package is bundled into a fully-vented, high-gloss chassis with a hand-rubbed, five-step, automotive-quality finish.
