For all those who will be attending... I think a lot of us will be especially interested in your impressions of Red Wine Audio's new version of their Corvina HPA. I understand it will have both single-ended output and balanced output - to improve it's peformance with both low impedence and high impedence phones.
It will reportedly be especially great with Audeze and HiFiMan phones driven out of the balanced output.
I'm particularly interested in how it drives "new version" Senn HD580 / 600 / 650's / 800's, as well as Grados, ATH's and Denon's.
