I’ve got a T2 (direct to my amps) and will likely upgrade to an X1 (or its successor) eventually.
I don’t find the X1s limitations to be problematic. I stream exclusively. I need a streamer and a DAC. I don’t ever plan to go back to physical media (or go through the tedium of ripping all my old CDs) so I don’t need an external digital-in, source selection or separate boxes.
The only thing that gives me pause is I think both DAC/Streamer tech is rapidly advancing, and will warrant replacement every 5 years or so. Doesn’t make much sense to me to upgrade too fast, there’ll be a better mousetrap every 3 years. Oh, and the T2 sounds fantastic.
