after i tested „Archphile“ with the Skysong-Xmos-USB-interface and still don´t know how to limit the DSD-rate to the DAC/-combo (it uses 705600 but the ES9038Q2M doesnt support it, i got only a heavy white noise), tried everything in the /etc/mpd.conf; i used again „Volumio“ as it said in one of their forums something about their DSD-native/DoP-compatibilty..
so let it run and hooray, the DSD-Led on the ES9038Q2M + the DSD-indication on the skysong-bridge were lit !!
(hadn´t got the DSD-indication before afaik).
wonderful, true DSD/DoP-sound !! 😉
had used foobar2000 with the Asio-driver/DSD-processor, the singxer audio-panel said:“Asio active(PCM-mode)-352800khz sample-rate“, see 2 posts before, but meanwhile i think it was converted !! to PCM- (with soxr by example) >because i hadnt got the DSD-led on and it wasnt not such a great improvement to „normal“ PCM..
now with volumio it sounds absolutely fantastic, absolutely real DSD-„sound“ !! („real“ DoP)
by that i´ve think meanwhile „Archphile“ is for the really high-end USB-DACS->384khz,768KHz (and above); think its about the „Arch-linux ARM“-kernel/core..
also u got a wonderful „Alsamixer-volume and master-clock“-mixer for the XMOS-USB-audio interface (with the command „alsamixer“)->
also interesting in Volumio is that if use the „resample-option“ in the settings it affects also the „DoP-chain“->set at 384khz resample/sox/very high, got my red light (PCM) on the bridge on and no DSD-light on the ES9038Q2M..
interesting II. is that u can resample up to 768khz (in Volumio) and u can hear something (but heavy white-noised) on the ES9038Q2M although somebody posted it can only play/(is capable of) up to 384khz in „asynchron-mode“; but i heard here something..->
greets for and more to come !! 😉
in trying to play finally some real/Native DSD on some (our „lovely“ 😉 ) chinese ES-Sabre-boards i came by chance about the „Archphile“-distro->https://archphile.org/ (knew about it , but hadnt got the time to test it till now)
it uses mainly the mpd-subsystem and i´ve read some days ago that it also could be a driver problem/xmos-usb-driver thing on linux to get DSD-native to work..!!
so and today after imaging the archphile-archive, and first i must say its really hard/difficult to „understand this archphile-distro“, because u got only a MPD-user interface with almost no settings (for the DAC for example and so on), u have absolutely to work over SSH in first place..
so but the really interesting thing is this->
first picture is the output of the „alsacap“-command (its Arch-linux)->
absolutely super fantastic !!! it says that the XMOS-USB-device (Skysong) can handle up to 768khz (via linux usb-driver)!!!
(a problem could (may) be that it didn´t show the „DSD_U32_BE“ sample-format which is normally a clear point/-„ means that this DAC supports Native DSD in Linux„.)
but anyway absolutely fabulous !!
and much more fantastic is that it sends 705600 !! to the xmos-usb !!!->(with the „perfcheck“-command)
by that, „Archphile“ has a very good/clean sound; sounds better than the picoreplayer for example (IMO), really,really clear !!
but got a really „destroyed/white noise“-tune with these 705600 on the ES9018K2M(and didn´t find a way here right now to lower it down to 352000 for example); have it really hard to work it out here at present; (the ES9018K2M has lower capabilities DSD-wise than the ES9028Q2M or the ES9038Q2M for example).
flacs (all up to 24/192) are playing very,very well..but anyway as said, really,really great news !!
more to come !! -> greets for now !! 😉
as said in this post->http://essabre-90xx-rpi.sfb2.com/2018/08/singxer-su-1-driver-update-v4-45-06-juli-2018-v7-24-i2s-hdmi-pinout-matrix-x-sabre-pro-9038pro/ i had now the time to test the V4.45 (we had V4.36 (Singxer_USBAudio_v4.36.0_2017-11-14_DSD512.rar)) on Win10 with a Skysong (Singxer) USB-XMOS-XU208 + ES9038Q2M and it sounds great (especially also on foobar in DoP)..->Link
i surmise its slighty slightly a little bit better (almost „hypothetical 😉 )(but in foobar in DoP (DSD128) its great as said)->
more about it (+file+link) in the forum->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=75
greets for now 😉
came by chance about this new „Singxer“ USB-Class-driver V4.45..we were at V4.36 and its directly from the same „shenzhenaudio“-folder/website->https://download.shenzhenaudio.com/Singxer/SU-1_driver_7.24_update/,
where we got our lovely „Singxer_USBAudio_v4.36.0_2017-11-14_DSD512.rar“ from; i will test it here; but my ES9038Q2M is now connected to the Pi; will see..(post the driver-pack at the forum too->Link)
The Singxer SU-1 is equipped with one ES9038Q2M + a XMOS XU-208->https://www.amazon.com/Singxer-digital-interface-XU208-DSD256/dp/B01N1OQY1A, https://kitsunehifi.com/product/singxersu1black/
by that i saw some I2S-HDMI-port pinout on the „Matrix X-Sabre Pro ES9038PRO 32Bit/768kHz DSD1024 Audio DAC„->https://www.shenzhenaudio.com/matrix-x-sabre-pro-es9038pro-32bit-768khz-dsd1024-audio-dac.html;
it says:“DSD1024 PCM768
As a new generation of Matrix flagship DAC, X-SABRE Pro not only supports 32Bit/768kHz PCM audio stream playback, but also supports DSD64, DSD128, DSD256, DSD512, and even supports DSD1024 with the sample rate of 45.158MHz via IS input port.“
(thats all „old“ stuff; but just to remember)
greets for now.. 😉
after i tested a lot of different op-amps+filter-settings on the ES9038Q2M (Blue) lately i came to this (final) conclusion:
The Muses 8920, are/“sound“ brilliant on these Blue, i think they are lately called „YJ-ES9038Q2M“ Q2Ms..
much better as with the NE5532 or the OPA2134 for example (other possibility would be the AD797, LMEXXXX (see earlier post))..
by that to provide the Skysong/Singxer USB-bridge with an external 5V power supply also boosted the overall performance of the Bridge by 10-15% !!
absolutely to recommend !! 😉
absolutely wonderful bridge (read elsewhere they should be the „finest“ with the best XMOS-implementation)..(i have the version with the golden crystek cchd957s))..
the filter-settings have here for me not such an impact on the sound/tone, guess 2-3%, max 5% 😉 , but u can hear it if u want..but the differences are really „paper-thin“ (on other DACs/millboards it could have a greater impact)..
by that „kennyliveforever“ made a great post in the forum-> http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=64 about how to include the „original“ essabre-driver (I-Sabre-K2M) for the ES9028Q2M in Volumio (and then maybe in other audio-distros)..
so far for now !!
and so, 😉
we are now here again with a main „Hi-Fi“-theme/problem:
„Clean-/clear-/power“ and Power-Supplies“ 😉 ..
It´s all about the right-/clean power, voltage-regulator-/stabilizer..
i´m very often in this very good forum concerning all these electrical things/also concerning the ES9038Q2M->
so, and i came again to this subject (matter), cause i had/these „stuttering“-problems again with the Skysong-/Singxer-USB-bridge+the ES9038Q2M..
first i thought it´s mainly a driver problem but meanwhile i guess it could also be a power-supply problem->5V on the USB-bridge via USB !! (500mA); could really be a problem(-„stable-wise“)..
I came by it because i (try to) made a DIY-power-supply with a 32V-HP-power supply for some printer + a cheap „Step-down-power regulator/supply“ from Aliexpress->
it had 625mA and i thought this should be enough cause i´ve read elsewhere that the ES9038Q2M only needs roundabout 200mA..
I connected my ES9028Q2M with this regulator and (adjusted it down to 15V) to my raspberry and got a horrible, horrible stuttering !!
thought first it was a software-problem but wasnt..asked some user in the forum and they told me that some power-supplies may become „unstable“ with/on „low-load“..
anyway this brings my again to the above „topic“ and now i think i better use a 5V-stand alone-power supply with minimum 1A for my USB-bridge (the Skysong-/Singxer have the possibility via a barrel-jack)..
by that i´ve ordered some other 15V-power supply with „stable“ 2A for the ES9038Q2M..
where we so come back to the main „theme“: Dual 15V for the ES9038Q2M and power-supplies in general..see above 😉
(the pictures are from „Markw4“ from the above mentioned forum; hope i can use them here, there are just to „illustrate“; if not please some e-mail)
thx to „Krunoslav“ again, he sent us some new driver (V4.38 from matrix-digi.com) to test perfect bitstreaming via wasapi under Win8.1+Foobar+Skysong(Singxer)-XMOS-USB-bridge+ES9038Q2M->see comments->http://essabre-90xx-rpi.sfb2.com/2018/02/es9038q2m-es9018k2m-dsd-perfect-bitstreaming-win8-foobar2000/#comment-50..
unfortunately it doesnt work here for me but i will upload it to the forum anyway (LINK)..but be careful i had here very great problems with my antivir..
but curiously after installing my buffer-/“stuttering“-problems with files above 16/44,1 (now here in 24/192 no problems) with the Skysong(Singxer)-XMOS-USB-bridge+ES9038Q2M (via I2S) are gown away 😉 ..
but still these new ES9038Q2M (in any case the pcb i have here->the „blue“ one) sounds for me still like plate/sheet..(„old problem“->we still have to evaluate if its a „shitty“ pcb/components and if the „green“ ones sound better)..
USB-> PCM 16-32Bit /44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz, 352.8kHz, 384kHz, 705.6kHz, 768kHzDSD DSD64/128/256 (DoP/dCS) DSD64/128/256/512 (ASIO Native)
because i have here heavy „overdue delivery“-problems for some Aliexpress/China-manufactored DIY-things (yesterday a Electric Soldering Iron arrived exactly after 94 !! Days), i decided to make a new try in DSD-(native)-playing under Windows..experiences so far:
(i used Win8.1 because i don´t want to fuck up my Windows10-settings with the XMOS-USB-driver)..
okay, i used foobar2000 (JRiver trial period is over 😉 ) and have here the Singxer-V4.36 driver installed..
I used the ASIO-tutorial in the Topping NX4DSD v4.14 driver and manual pack (->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=22) because i heard absolutely nothing with the „ASIO-Singxer USB Audio Device“-settings under „Preferences->Output->Device“..
after installing the foo_dsd_asio and foo_input_sacd foobar components + Asioproxyinstall v0.72 from the Topping V4.14 pack i´ve finally got a heavy white noise on both channels with the ES9038Q2M (and very very silent music back in it) and heavy white noise only on the left channel with the ES9018K2M (both with the Skyong(Singxer)-USB-bridge))..
The Singxer USB-Audio Device Control panel displays (in this case) 5644800hz and foobar also shows:“DSD128/11290kbps/5644800hz“ and the DSD-light on the ES9038Q2M and the blue DSD-led on the Skysong are also lit (see picture above)..
i´ve read elsewhere exact the same behaviour/problem..
okay, but this is a small improvement, because with the normal „Asio-Singxer USB Audio“-driver i heard absolutely nothing..
so far for now, i really have no clue to progress further (as said didn´t test it on Win10 because of not messing around with the usb-driver there)..
If anyone here has a solution for this „white noise“-problem, please leave a comment here !!
