I did not like the Lyr paired with hd800, t1, or really any headphone other than thunderpants and lcd2. I could never get the noise floor silent and it drove me nuts. I recently sold my lyr for these reasons.
I felt the concerto handled my hd800 much better and did almost as good a job with the lcd2. I'm a big fan of the concerto, seems to work well with every headphone I have ever thrown at it. It must be the active balanced ground or something.
I have not heard the v200, but for the hd800 I'd prolly prefer it over the lyr based off what I've read about it.
