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 !!
because i have here really heavy problems in playing anything above 44,1/16bit due to buffer(and/or driver)-problems (on a raspberry the ES9038Q2M works perfectly) on a Skysong (Singxer)-USB-bridge and a ES9038Q2M („Blue“) i came by chance across this Topping NX4DSD..
it has also a XMOS-XU-208 and a ES9038Q2M „onboard“; interesting is the specification:
„16/32bit 44,1-768khz + DSD512 (native)“ and (whats more interesting):
„NX4 DSD use costum driver from Thesycon“..
so, and thats the thing here..the „normal“ Singxer USB-Audio Driver 4.36″ does not work here satisfying with a ES9038Q2M..
2 possibilities: we get in future an update for also playing on this ES9038Q2M without problems from Singxer or we can get some custom made Theyscon driver which matches „our“ Skysong-Bridge+the ES9038Q2M..(any help here is really appreciated !!)
i´ve anyway attached here (and in the forum) the original Topping NX4DSD driver+manuals, which were btw. very interesting in setting up JRiver for perfect bitstreaming..(u have to use completely the ASIO-driver/interface..))
the Topping NX4DSD driver/manuals is the version V4.14..->NX4 DSD Manual and Driver V4.14->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=22
first, i must say: „Unbelievable“ 😉
(first impressions after arrival:„looks very neat and very well manufactured !!“)
hadnt expected so much; just wanted to uprade my PC-soundcard a little bit (Asus Xonar DX) and get rid of those horrible clicks/pops on the raspberry pi..
use now my „ES9018K2M“ cause i dont wanted to f*** up my raspberry-setting with the ES9028Q2M..
and now i know what i already knew 😉 , that the ES9018K2M were already „High-End“ in the right circumstances/surroundings..(and they were implemented on these/our „cheap“ chinese-boards with low-quality components !!)
i also read somewhere that our lovely chinese-boards were specially designed for XMOS-USB devices; don´t know if its true but i can confirm that it is almost unbelievable what i now hear here ;-)..
so „dry“, such a lot of details, spaciousness, so less latency..
(it really upgraded my hifi-gear by 10-15%, and i have here a Cambridge Audio-Amp and Mission Cyrus Speaker)
okay, use now the standard-Win10-driver; had problems with Win8..
„Krunoslav Kovacic“ send us fortunately the driver for the Skysong/Singxer for DSD on Win10 (hadnt test it yet by myself) and moved it also to the forum..(and some „standard“-driver)..->http://essabre-90xx-rpi.sfb2.com/forum
it says „XMOS USB Device“ and „Skysong DFU“ in the device-manager..absolut no hassle or problems while installing..
u can select up to „24bit/384khz“ in the audio-properties->(see picture)
VLC-player plays 192khz but no more; Windows Test works with 384khz..
use now here JRiver („XMOS USB Audio-WASAPI“) will test then foobar, ASIO etc..
(and this is all on a PC; hadnt started the whole Raspberry/Dietpi/Moode-thing right now 😉 ..)
Conclusion (for the moment): absolutely super to recommend !!->47$/39€ inkl. shipping (23 !! days to deliver from this seller)
