I auditioned the new Decware amp a few months ago. Amazing build and sound quality, with a lot of useful features. Music floated in space, and there was great drive and dynamics. I think if Decware sold through dealers it would cost at least 2-3x the cost they charge direct. Amazing value and I love how they let you configure on the website to your exact requirements.
For me, the merry go round stopped when I found VAC. I just sold my VAC 300.1a amp and am awaiting my VAC 450S. It nails harmonics, speed, resolution, musical drive, timbre...when I listen to VAC it stops being an electronic reproduction of something, and I immediately see the instruments and vocalists. Kevin Hayes at VAC, to my ears, has reached audio nirvana with offerings. My solid state amp is the Conrad Johnson Premier 350, which is definitely a keeper...so much goodness in one enclosure.
