I'm extremely happy with my Dialogue1. I also currently own two Cary amps, a V12 and 300B SEI. Over the years I have owned many top brands including ARC, a RM10, Forte 4, and so forth. The Primaluna amps travel in that company. High build quality, easy to use, tube rolling a delight with the auto bias feature, tailor your sound as it takes many different tubes. I like its looks; but, most important they sound really good to me, all the audiophile attributes are there in spades. System synergy is important as always. And Kevin Deal at Upscale is a first rate high end distributor.
