PrimaLuna DiaLogue Two Stereo Integrated Tube Amplifier

ARTICLE INDEX


Introduction

The PrimaLuna brand needs no introduction to the tube-loving community, but I do (did). Though I've heard plenty of good sounding tube gear at shops, at various friends' houses and of course at shows, I generally listen to solid state equipment. So, having the PrimaLuna Dialogue Two here for review was a new, and very pleasant experience.

From what I can tell, the most strenuous tube advocates listen primarily to Jazz. They can tell you all John Coltrane and even about the difference between a KT88 and 300B, but mention M83 and Four-tet and they might think you are trying to sound smart by making up heretofore unknown tube types.

I don't need any convincing about the sweet sound of tubes though. As a kid, tube gear was all I heard. Everyone on the block had a tube powered console stereo. I think ours had the best sound. My neighbors were fond of playing Alice Cooper on theirs, so loud that the proper listening level was found about a half block away. Yes tubes can play loud. And the half block soundstage indicates that tube amplifiers definitely can have headroom.

In spite of my solid state bias, PrimaLuna fearlessly offered for review their DiaLogue Two integrated. PrimaLuna designs their products at the headquarters in The Netherlands, builds them in China and sells them in the US through a number of dealers.
