I think the Burson is a good amp (I own one too), very detailed, dynamic, punchy, forward and engaging, but I think it's a little too bright, especially for the T1's. After trying other amps, I don't think it's an ideal match. I've heard good things about the Graham Slee though.
Well, actually it's all back to our own taste, but most of the time people who try my Burson(s) usually said that this amp is more to dark rather than bright. YMMV of course, no one is wrong :)
Graham Slee is more mellowed than burson, so for vocal stuff perhaps it will be a better choice.
note: In my local community seems like many people also like to pairing T1 with Burson or GS Solo :)
