I'm listening to my T1 as well at the moment. I love them. They are pretty similar to the DT880 but they are just better across the range. And the bass is so freaking fast.
I'm still waiting to get my Wyred 4 Sound DAC2 delivered, I can no longer wait :(
By the way, the SPL auditor is a really good amp with the T1 for what it worth (since it's the only amp I have ever tried).
