PrimaLuna DiaLogue Premium Integrated Amplifier
Don't buy good. Buy perfect. Iconic. State of the art. Something that will still be relevant ten years from now and that is built to last a lifetime.
Thinking of buying an amp because of good reviews? Every product, no matter what, gets good reviews. So how do you know if it's simply good or world-class?
The answer is simple- When a magazine reviewer spends their own money to buy it for themselves! Many reviewers have done just that because every PrimaLuna reviewed has a Stereophile Class A rating. Class A is defined as "Best attainable sound for a component of it's kind, almost without practical considerations" with practical considerations meaning at any price. The Absolute Sound's Dick Olsher is possibly the most experienced and technically adept writer on staff when it comes to tube amplification. He declared "It is my current benchmark in integrated tube amplifiers," resulting in a 2014 Editor's Choice Award.
Sure it looks good. But that should never be a reason to buy. Don't be fooled by overpriced name brands and lofty descriptions that cover up mediocre build quality. Do you want an $8000 integrated amp weighing only 36lbs with one printed circuit board, no-name parts inside, and a push button chip volume control? Or a $3399 integrated weighing 64lbs, hand made with Swiss point to point wiring and the finest exotic parts, and the most advanced technology found in any tube amplifier? Any audiophile who is also an electrical engineer would know instantly.
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.
