I bought the X10T for around $160, during the Ali Express 7 year anniversary. In all honesty I've not used it all that much, because of the lacking user interface (looks similar to the X10 pictures in the first post) and the lack of gap less playback.
It sounds all right, paired with an XD-05 (Burson V5i-D). I'm waiting on an optical cable that will fit the Chord Mojo, and will play around more after that.
Not sure what one should expect with these budged transports, but I think it's kind of poor that the player don't support DSD128.
On the other hand, no problem feeding it with SanDisk Ultra 200 Gb cards. So there is no 128 Gb limit to the SD cards.
My unit is on firmware V1.11, and I have not found any updates at
