The Meier Classic is a good pairing with T1 IMHO. Infact I believe one of the the HP's he uses while voicing the Classic is T1. he in fact recommended the T1 when asked which HP pairs best with his amp.
I feel the T1 anemic with Corda, specially at low volumes.
With HD650 i get the wow factor, with T1 , nope...
I dont know, sound perception is something subjective
