What HFL Thinks

PrimaLuna DiaLogue Premium Amp - At HFL we wanted to offer our customers a Valve alternative to the many solid state systems out there and after looking at all the options we always kept coming back to PrimaLuna for many reasons. Firstly they look amazing and are built like a tank, they are designed to last a lifetime and are affordable offering a performance that is hard to believe for the price, also they are extremely easy to live with, with features like Adaptive AutoBias & SoftStart circuitry amongst other features they really are an everyday product that can just be enjoyed. So Please come into HFL and be prepared to be swept away by the beauty of the valve sound with PrimaLuna.

The bar has been raised...

The DiaLogue Premium series has set the bar for what an all-tube integrated amp should be: Sexy... exotic... and built with exceptional features not found in any other amp in its class including:

  • Adaptive AutoBias . As with all PrimaLuna amps, you never have to worry about biasing your amp ever again.  You can even just flip a switch, and the board is re-calibrated for EL34s or KT88s (or KT120s). Every DiaLogue Premium Series amplifier can be ordered with either set of power tubes installed.

  • All critical signal paths are wired with silver-plated, oxygen-free continuous crystal (OCC) copper with a Teflon dielectric for superior signal speed and increased clarity.

  • Premium parts from around the world including ALPS volume control and Takman resistors from Japan, and SCR tin foil capacitors made in France.

  • Exclusive AC Offset Killer. This piece reduces transformer hum, resulting in lower noise and the blackest background ever.

  • New front-end circuitry. The DiaLogue Premium uses three 12AU7 tubes per channel, plus further refinements to the ProLogue Premium circuit.  The result is even lower distortion and increased bandwidth.

  • 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!

  • All the features found in the award-winning DiaLogue Series:   Full-function remote, Triode / Ultra-linear switching, Home theater bypass circuitry, all in an amp that is point-to-point wired and designed conservatively to extend the life of your tubes as well as critical components inside the amp.

The DiaLogue Premium Series also includes the same innovative circuits found in the ProLogue Premium series, that protect the amp at every level:

  • BTI-circuit. BTI stands for "Bad Tube Indicator." On the chassis’ deck in front of each power tube, is a small LED that lights up if the tube goes bad. This circuit works hand-in-hand with the new Adaptive Auto-Bias circuit.

  • PTP-circuit. If the power transformer should overheat, this "Power Transformer Protection" circuit cuts primary power, allows the amp to cool down, then resets itself.

  • OTP-circuit. The "Output Transformer Protection" circuit protects the output transformers in the event of a massive tube failure or user error.

  • +B relay. Replaces the plate fuse and works in conjunction with the OTP-circuit to protect the amp against tube failure. This method is less intrusive sonically and the relay resets itself once the faulty tube is replaced.

As with all PrimaLuna components, the DiaLogue Premium Integrated is made by hand with the finest point-to-point wiring and quality equal to—or better than—any product you can buy at any price. All packaged in a high-gloss, hand-rubbed finish.

HiFi Lounge have been big fans of Bryston for many years now, owning much of their equipment personally before starting HiFi Lounge. We even started the always active Bryston Owners Thread on AVForums to which we contribute regularly, so it really is a privilege to be part this new scheme. We have a vast knowledge regarding the current Bryston range of which we have most on demo, so if you have any questions or would like to come in for a listen please do not hesitate to get in touch. There is nothing we like more than talking about and listening to Bryston equipment.
