The bar has been raised… again.
The DiaLogue Premium preamp is everything you love about the DiaLogue Three; and more. Like the DiaLogue Three, the DiaLogue Premium Preamp is a dual-mono designed preamp, and weighs in at a hefty 53 pounds. Much of that weight is thanks to the pair of heavy-duty power transformers–already recognized as a reference in the industry–that provide increased control and detail. In the unlikely event that one of the transformers should overheat, DiaLogue’s innovative new PTP-circuit cuts the primary power, allows the unit to cool down, and then resets itself.
However, unquestionably the most significant feature is front end circuit. We start with the award-winning circuit found in the ProLogue Premium and DiaLogue Three, then take it to new heights by using three 12AU7 tubes per channel instead of two. As a result, bandwidth and resolution from top to bottom receives a significant boost. Just as important, the additional tube in each channel also cut the preamplifier’s output impedance to only 256 Ohms… meaning the DiaLogue Premium Preamp can mate with even the most demanding solid state amplifier with no sonic drawbacks!, distortion levels in the first stage have dropped by a factor of five at low levels, to at least 20 at higher levels, above one volt.
Next, we add the highest grade parts: Silver-coated, continuous crystal oxygen free copper wiring with a teflon dielectric is used in all critical circuit paths. SCR tinfoil capacitors made in France, and Takman resistors made in Japan are used throughout the preamp. A special AC-offset killer (another PrimaLuna exclusive) reduces transformer hum, making the preamp just as absolutely quiet as possible, without sacrificing performance.
The DiaLogue Premium Preamplifier also comes equipped with all the standard features found in the DiaLogue Three preamp: five pair RCA line level inputs for maximum versatility, one pair RCA tape out and two pair RCA preamp outs. A home theater pass-thru circuit that promises to keep everyone in the family happy. Finally, it comes with a stunning, heavy-gauge, anodized aluminium remote that controls all functions of the preamp.
All these exceptional features come encased in the exquisite DiaLogue chassis, with its five-stage, hand-rubbed, high-gloss, black sapphire finish.
Also available with optional MM phonostage. $249
