With a laptop/Itouch 3g -> TF10 setup, is the sq of the t3 or uDac noticeably better than the E7 for the price?
If you are only getting the uDAC, then you won't be able to use it with your iPhone. If If you are only getting the T3, then you won't have a DAC for your laptop. However, If you get a uDAC for your laptop and a T3 for both laptop and iPhone, you will be spending almost 2.5 times more than an E7 is going to cost you. I think I would be very sorry myself if uDAC and T7 combo doesn't turn out to be noticeable better.
