PrimaLuna DiaLogue Premium Preamplifier Ex Demo

DiaLogue Premium Preamplifier

At PrimaLuna they believe in superior engineering and superior parts. That is why they use Swiss-made silver-plated OFC wiring, Mundorf capacitors from Germany, and from Japan, Takman resistors, Nichicon capacitors, Fujitsu relays, and Alps volume controls. Parts well-known for their superior sound quality; quite literally, the best of the best.

SMARTGAIN DESIGN

A preamplifier is typically not required to add a lot or even any gain to your system. It is usually lowering gain from the source you are listening to. The number one complaint from audiophiles about preamp performance is noise. So why is it that so many manufacturers design preamps with 20 to 27dB of gain? And you wonder why there is "hiss", and why tubes go noisy or microphonic? PrimaLuna preamps use SmartGain. With a gain specification of only 12dB, you will find your PrimaLuna preamp is as quiet as a church mouse. High efficiency speaker owner's rejoice!

PERFECTMATCH

Another exclusive PrimaLuna feature is PerfectMatch, a circuit designed to present a perfect 100K ohm impedance to your source components. This is vitally important especially for tube source components, such as phonostages and DACs to sound their very best.

SUPERQUIET LINE INPUTS

Input selector switches leak noise and signals from other sources, as they never turn off the other inputs completely. And, they deteriorate with age, requiring the use of cleaners. Many are mounted on the front panel requiring long runs of wires to the back panel inputs. These wires pick up stray noise from RF and EMI.

PrimaLuna has a better way. Instead of a switch, input selection is done using premium quality sealed relays mounted in the rear where you plug in your components. When an input is selected, that relay closes giving you the best connection possible. All the other relays are left open, so noise and signals from other sources can’t leak in. The signal path is now almost non-existent, so there are no wires to pick up noise.
