Nice headphone
D ) amp. Is that the one with the WE tubes?
For reference, a couple of weeks ago, I was running the Audio Aero here at home, hooked up using balanced outputs into my Stax Omega setup. I can say that for me, that was one of the finest music makers I have ever heard. The midrange was quite glorious, warm, detailed and involving. One evening I sat listening on that rig for four hours straight.
One thing to bear in mind would be that the combo didn't really suit headbanging, due to the relatively low output, and the tubes in both the player's output stage and the SRM-007T. Still for most music, it really was a dream, and I suspect that, given your current use of the Cary, would be a very suitable match.
The Audio Aero has switchable voltage, so you can buy from the UK or Europe and take advantage of any savings.
