So I have my WA22 setup, and all I have to drive it is a Marantz DV8400. Not a bad piece, but definitely not the right piece for the headphone amp. So I went shopping. And found exactly the right piece. Balanced tube outputs and very highly reviewed. Im not very familiar with Ayon, but like what I read.
And the silver finish and blue backlight on the buttons matches my amp. Should have it by the end of next week.
