Would there be any significant difference on the streaming output (to an external DAC) from a T2 vs using the U1? It looks like the digital output specs are pretty much identical.
For output to external DAC, U1 is better than T2 / U1 MINI due to the LPS of the former.
For digital output, T2 only has USB and BNC outputs.
In addition, U1 and U1 MINI add AES, RCA and toslink outputs.
