They both have different presentations. The UHA6 MKII focuses on depth while the T1 has emphasis on both depth and width in the sound stage. For me this makes music that much more pleasant to listen to from the bass, treble to mids. They all make each other that more apparent and enjoyable IMO. So I feel they are similar in terms of overall detail but their presentations are quite different. In a sense I can say it is easier for me to perceive the detail on the T1 as it is that much more engaging for me. This is with my DX100 however as it pairs extremely well with it. The UHA6 did excel on my DACport LX though since the DACport had a good width to it's sound staging so they blended well together.
4As or 4ai? ;).
