as we had it here in discussion:“is it possible to get real (native) DSD/Dop on the ES9038Q2M to work ?“ (with the DSD-lock-light on<-thats important because foobar for example indicated „Dop“ but it is internally converted to PCM and the DSD-lock-light stays „off“)
in my experience here now/to date u can get it only with Volumio (or similar) and via an usb-connection to an usb-xmos-device and from there via I2S to the ES9038Q2M/Pro etc..(its also about the native-usb-audio-driver in linux)
I didnt got DSD to work via the „normal“ I2S-connection on a Raspberry for example..(and i/we tested a lot..)
I have now here a DSD256-file, playing it in volumio with the following settings: (for newbies 😉 )->no mixer, no resampling..
interesting is the separation from the device + power supply.. it is the same principle as maybe earlier with the Mission Cyrus Amps 1-3 with an extra PSX which cost the same !! (and i had luckily here) and which remind us of the great importance of a clean, strong power supply !!
so, 😉 after i´ve re-checked my Op-Amp-„collection“ 😉 (in testing them on an ES9038Q2M) and reading a lot of op-amp reviews again, i´ve ordered a few days ago some AD797BR(Z) (as described in some posts before).. The „B„-line has a stricter factory-selection/-fabrication and is mainly considered as the best AD797 for audio.. by that, curiously, i got the most the site-/page-visits here op-amp-wise, means the main interest is also in the op-amp-section/part/reviews.. so i can/will hopefully test them in a few weeks and the next step (op-amp-wise) would be the „Burson V5/-6″-line..
some good toroidal transformer (+-15V) cost also about 30-40$ (min.) and so i/u have to check out which will bring the best „tone/sound“-enhancement (or both of course).. (Link-Aliexpress or from Audiophonics or something) „Webcontrol“-ESP32-wise its still in development but primary i think i want now to search for the right case, transformer.. many greets from here for now 😉 (some pics of pc/-hifigear with Burson´s + also a pic from a Gustard H-10 with V6s)
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.“
so, 😉 thought about an upgrade to an ES9038PRO by example.. we´ve had here a post to a „HIFIME UDA38PRO DAC“->http://essabre-90xx-rpi.sfb2.com/2018/02/es9038pro-new-es9038pro-out-hifime-uda38pro-dac-es9038pro-sa9227-219e/, 219€ and now looked today through Ebay and found this one: roundabout 190$..->LINK looks very nice manufactored, nice layout, 4 Op-Amps.. very interesting is also that they recommend: „..default include NE5532*2 + NE5534*2 Op-amp you can upgrade the op amps :AD797 AND muses8920“ (have absolutely the same opinion here too (and also at the „DIY-audio.com-forum“; link at the right..)+ our „fabulous“ „OP-Amps recommended by ES-Sabre“-list->Link..
so, but nevertheless i must say that as i heard my combo („Blue“ES9038Q2M+Muses8920) after a little timely distance it is already a superb fine tune/sound..(but as said, u have to use Muses8920 or AD797 or similar)..
by that, some user at the phenomenal DIY-audio.com-forum->Link at the right link-list also said that he also has the impression that the „Blue“-ones sounded „flat“ (as i said/posted before)..
so because it is already a really fine sound/tune here, and this 200 bucks are to expensive for me right now/at present i guess i will maybe order some „Green“ ES9038Q2M (V1.06 or V1.07)->but/and „we“ have to be very careful in selecting the right ones, because there are also absolutely great differences on the „Green“-layouts concerning the quality of the layer+components !!)..->selected „Green“-one (V1.06) for now: Ebay 36€->Link (interesting feedbacks/ratings btw. !!)
i´ve ordered some LME49720 and will test it against the Muses (next step would be to buy some AD797 or 2 LME49710)..
so i think its the best for now to stuck and further „experiment“ with the ES9038Q2M !!
(and provide it with some really great „Talema“ or something/similar 😉 )
so, 😉 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)..
