So what makes this preamplifier so good? It comes down to the build quality, the quality of components used, and the features the PrimaLuna DiaLogue Premium Preamplifier offers the end user. For example, it has a dual mono design and includes Adaptive AutoBias, TAKMAN Resistors, SCR Tinfoil Caps, AC Offset Killer, Point-to-Point wiring using high-end silver plated OCC copper with Teflon dielectric, ALPS Blue Velvet volume control, etc.
What we really like about the is preamplifier (and all PrimaLuna products) is how easy they are to own. PrimaLuna has taken all the stigma about owning valve based amplification out of the equation. And for this reason, everyone can now enjoy the naturally organic sound valves produce.
But like anything else out there what do these features really mean? Simple, the quality of sound that this preamplifier offers is awesome.
One of our favourite feature found in use in this preamplifier is two 5A4R tube/valve rectifiers (one per channel). Rectifiers transform the AC voltage to DC voltage. Most valve based preamps use a solid-state rectification; this wasn't good enough for PrimaLuna and they decided to go with the much more expensive tube/valve rectification and our hats are off to them for doing so – and once you hear it, you'll thank them as well.
We have mated this with many different power amplifiers and with great success. We love the ability that the PDPP has of bringing the listener to feel like they are at the place (concert hall, studio, etc.) during the recording session. Such a lifelike presentation is hard to find, but not so with this beauty.
Having this as the “brain” of your hi-fi system is going to take it to the next level.
