To all those looking for amps for T1s. I had a WA2 for some time and then switched it to Corda Classic. I have to say that I am very pleased with the end result. As much as I liked he WA2 and its more relaxed signature with T1s, I love the Classic even more for the transparency. I much prefer the Classic now and would not change it now.
Note: I have the non-basslight ersion of T1s (provided that you believe there are two versions of these headphones)
