I too think it would have been nice, if the Touch was capable of SPDIF or USB Digital-Out, and I don't think there was anything wrong in what you said.
On the other hand, what you are doing is Selective Criticism. Sony 1Z also costs $3k and lacks some features that some of the sub-$1k DAPs offer, yet, I have never seen you calling Sony out for 'Milking' in the 1Z thread. Nor did you mention the lack of those features as Cons in your review.
i) The device can't act as a USB DAC
ii) Does not have PMEQ
iii) Single Ended seems to be intentionally choked down in terms of power 60mW through a 32Ohm load (vs 250mW on 4.4 Bal) and can't play DSD via SE. So one has to get a Balanced Cable to get the best out of the player has to offer
iv) The internal wiring is sub-par
v) Uses proprietary USB connector
I am not trying to make this into Lotoo Touch vs Sony 1Z post. Just saying, if you want to be critical about the Lotoo DAP, you need to be fair and be critical about the Sony DAP too.
