SMSL DP3 un petit lecteur réseau surprenant et performant

[renan]

The expansion of the stereo base in DP3 is done simply: the signal from the main channel with an 18dB level and an inverted signal 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.

So in fact you told Hiby and SMSL something they already know, if it was done on purpose...

If this is done on purpose - it should be able to enable / disable.
All the same, this is not a toy for $ 20.

I agree with you that it's certainly cleaner by suppressing that crosstalk with your firmware. But after DP3 will be like many other streamers.
With that trick it might attrack buyers looking for some sound more vintage or other and you sell more DP3. The market is saturated, to sell you need something different.

What bring you do perform some measurements? what was your first impressions earing the DP3? what was the initial qualities highlighted for the DP3 in the russian forum? I'm curious about how it begun...
