Moode/Volumio on a raspberry pi vs. Samsung Bluray-player (spdif-coax) Impressions..+SRC4392 (+beta „Project 2“)
hi there, 😉
long time not seen..its a little bit silent here lately but absolutely no worry/problem..
i´have here some Samsung Bluray-Player (BD-H5500); not the worst; only with some spdif-coax output..
some days ago i thought the only, true,real good sound is via some very good CD-transporter/drive/device + directly via spdif into the ES9038Q2M and go 😉 ..
but as i heard today again the ES9038Q2M with the raspberry pi (Model 3B) and some flacs i felt its really a class of its own !!
1-2 level (soundwise) higher !!
(at present btw. i think Volumio (hated it a long time) has a very good sound/tune; a bit better than Moode 4.1 (then picoreplayer and so on)..DietPi (V6.8 now) is still „in the lead“ (IMO) but usability-wise Volumio is great..)
so, back to topic: i really don´t know why the flacs on a pi (and via I2S) had a such great sound/tune in comparison to some „normal“ CD-spdif-combos (IMO)..absolutely don´t know why; but it is (and this is said by really a lot of people in the „Hifi-world“ ;-)..(maybe its because of this delta-sigma-conversion and the „required preliminaries“)..
by that i think meanwhile the spdif-„conversion“ on the ES9038Q2M could be a problem; its not soo high-class/hi-fi as expected..(spdif-receiver-side)
in my praised DIY-audio-forum->http://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-129.html, they are looking lately for some „SBC 4392“ asynchron frequency decoder boards for spdif/usb decoding with 144 db !! thd and ultra-low jitter too..
think absolutely the same here and because only of „hearing“ out the „distortion/jitter“ via the spdif-receive-unit/decoding on the ES9038Q2M..
(so to see u must use such a SRC4392 before your ES9038Q2M and then via I2S in it, bypassing the onboard-spdif..)..
so, by that i definitively want to try out some AD797 in future (have now some Muses8920 in it) and i also want to buy definitively a new, „Green“ ES9038Q2M V1.07 because i still think the „Blue“-ones (have one here) sound really not so hi-fi as they could/expected (we discussed it here a few weeks ago)..
by that i revive my „Project 2“ a little bit; means BT/Web-control for the different-filter+HW-Volume settings on an ES9038Q2M (u can meanwhile buy it as „set/package“ with display and rotary encoder/apple-remote but nevertheless)
this time i used some „Geekcreit ESP32S Devkit-V1„-board (links/first thoughts about also at the forum-> link-FORUM ) (first post)
(ESP32S connected to a PCF8754 via some 5-3.3V logic-level-converter, controlling a 4-port relay and then to the 4 jumper on the ES9038Q2M..HW-volume via some MCP4131 will come hopefully later..)
but as said earlier, i hear almost no differences between the filter settings on these ES9038Q2M, but when, i would prefer JP3+JP6=“linear phase fast roll-off„
(as said, here now listening to it with this filter-setting on a pi with Moode 4.1; and so „dry„; absolutely low latencies, perfect (but as said, Volumio/DietPi sound a little bit better (IMO))
many greets for now 😉
