Haven't heard the 744T, but have heard the 722, which I assume uses the same converters and I run a MiniMe. They are very different A/D converters. The 722 has a very clear, open, and spacious A/D and is probably the best I have ever heard. The MiniMe does not resolve to the degree of the 722 and is brighter on the high end, too much so IMHO. That said, I actually prefer the preamps in the MiniMe over those in the 722 (neither are perfect), so what do I know. You really can't go wrong with either for the A/D, but if you are using it as a pure A/D, the 722 really can't be beat.
