I have my 2nd A7 online now and I've got to say, I really like the controller interface. One of my Controllers still has not arrived yet but I really like having the 2 A7's in daisy-chain also. I like the way the CGMiner Status shows each A7 separately in the Avalon Devices Status at the bottom. And I like that the two together are humming along at a 13.5TH/s clip here on the Kano pool!
Can you elaborate on whether you expect to have improved performance with each A7 on a separate controller? Obviously it would provide some relief if a controller would go out, but other than that would it improve performance? I have two A7's on ckpool with one controller and am getting well over 12th in 18 degree C ambient room after about 18h.
