thx to this phenomenal (post) in the diyaudio.com-forum->https://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-278.html,
we have now here our AK4137 as a single HAT for the Pi !! 😉
as said in earlier posts, we have to improve the signal-quality(lower jitter and so on) over I2S->http://essabre-90xx-rpi.sfb2.com/2018/06/srcs-ti-4192-ak4137-volumio-update-foo_dsd_asio/
it costs only 30 !! $ and u can get it here->LINK
„..The main function of this board is to improve the quality of the Raspberry Pi I2S signal and reduce jitter. And make up for the Raspberry Pi I2S output without MCLK! The original I2S output of the Raspberry Pi does not have MCLK and most high-performance DACs require MCLK to work. And the AK4137 reconstruction clock reduces the Raspberry Pi output signal jitter enhancement.
This board supports Raspberry Pi 2B 3B 3B+“..
so, as also posted earlier the AK4137 has 768khz (PCM) + 12.288 MHz DSD and DR: 186dB !! ● THD+N: -150dB ->AsahiKasei(AKM) datasheet->Link
(u use it between the Pi and our ES9038Q2M for example..a really long explanation on the other functions of this HAT is in the ebay-description above)
by that i came by chance (and according to the previous post) about this „Sonore ISO2DSD„-converter (a GUI for the sacd-ripper) + „Sonore DSD2FLAC„->
u can download both from here:
many greets for now !! 😉
by searching for the right settings to play real, native-DSD i came by chance about this tool->TEAC Hi-res-editor (WAV/DSD/DFF)
very interesting was, and thats why i post it here mainly, is because i couldnt play (flacs) above 192khz in VLC for example in Win8.1 (Win10) with the XMOS(Skysong)-USB-bridge and our lovely chinese-sabre-boards (ES90xx..)
i could select 24bit/384khz in sound-properties (XMOS-USB-Audio), could „generate“ a test-tone, but playing flacs in 384khz by example was not possible..
I´ve installed this „Teac-Hi-res-editor“ and surprisingly i had my 384khz (VLC) in Win8.1(Win10) !!
think it had installed some driver from which i was not aware of before..
second, the main very interesting feature of this Teac-Player/Editor that u can select the different DSD-rates (DSD64-2.8M,DSD128-5.6M and DSD256-11.2M) via the „play-frequency“-dropbox and it switches/plays through it->the Skysong(XMOS-USB)-bridge „clacks“-through and changes the LEDs accordingly to it !!
wonderful and absolutely easy !! (i had the ES9018K2M connected and have unfortunately a white noise at these rates (the PCM-rates up to 384khz are working well), but will test it with the ES9028Q2M and the ES9038Q2M)..
anyway, absolutely simple and very prolific !! 😉
(u must change the audio-driver in the audio-driver settings to „ASIO“ of course-> see pictures..but soo easy, great)(if u have no „ASIO->(XMOS USB)“-option try to install the xmos-driver V4.36 or V4.45 again (here singxer/skysong-driverpack))
greets for now !! 😉
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 😉
some user at my praised Diyaudio.com-forum->Link said something about a new MShow-Audio „SU5-ES9038Q2M-DAC-HIFI-XU208-DSD-TPA6120-Headphone-audio-Amp-Bluetooth-5-0″->Link 160$, and interesting is that they used some AK4113 for SPDIF-conversion; posted here earlier something about it->Link; for me another „indicator“ that the „original“-spdif conversion by the ES9038Q2M on this board is not soo good as expected, as stated also earlier; better choice would be using some SRC4192 or AK4137->Link
by that, as thinking to buy some Green ES9038Q2M V1.07, including the display, i found some pictures with this display delivered/attached in „action“ and that looks not soo nice (frankly said) 😉 , so i think its better to continue to try to build an „own“ version (display-wise) 😉
by that i´ve bought some new Raspberry pi 3B+ (cause i´ve „fucked“ up my Raspberry Zero W with some ugly soldering) and first thing i can say about the new „wifi“ (N/AC) that i had yesterday (measured with iperf3) 84Mb/s (10MB/s) via N (Asus-RT56U); not soo good (expected 300mb/s)..
greets for now 😉
nothing spectacular new, essabre-90xx-rpi has now „teamed-up“ with Allo.com,
where u can buy such nice things like the „Allo Katana DAC“, LINK
or some „Vana-Player“ for example; LINK
or the phenomenal „Kali-Reclocker“ (64€ (incl.shipping)); LINK
and also some accessoires like this 5V power supply (3A) 13€ (inkl.shipping)..; LINK
will try to make some „deal“ with them that u as a essabre-90xx-rpi member or visitor get some kind of „voucher“-code or discount or similar..
greets for now 😉
