Regarding the crosstalk, I use frequently a crosstalk correction done by Thierry69 on the forum (you can look at https://www.homeaudiofidelity.com/
So when I heard the DP3 for the first time on a friend's system, The sound coming from the DP3 was a little bit like the crosstalk correction. In fact it's a kind of stereo enlargment, the sonic scene is larger with the sound kind of out on the left and right of the speakers. This effect is quite sensitive the the cable quality.
This is why I suspected some kind of DSP mode in the DP3.
...
The expansion of the stereo base in DP3 is done simply: the signal from the main channel with an 18dB level and inverted is mixed into the opposite channel. An old trick, I have it in the 1979 Sanyo M9998 boombox. The problem with DP3 is that this effect is independent of frequency (it must be smaller at low frequencies) and there is strong distortion at the signal peaks (look at my oscillograms). In any case, I think that the player should give a clean, unprocessed signal at the output, and then you can do whatever you want with it.

If this is done on purpose, it must have an enable / disable function.
All the same, this is not a toy for $ 20.
