Really? How come?
I have the T1 and the TH900. If I WERE to let one go, it would be the TH900 based on its performance on my specific setup.
I adore the T1 on the Soloist. The TH900 sounds great, but feels like it is not up to scratch when a-b'ed with T1. Holding off making any decisions though, until I am able to test the TH900 on some more amps at the Auckland NZ meet.
