no worry about the ES9038Q2M 😉 there are new ES Sabre-audio-chips on the way/in the pipe.. 😉
and because this is an audiophile-site i present here some (mobile-)DACs from time to time..->http://essabre-90xx-rpi.sfb2.com/category/dacs/
came by chance about this thing on Massdrop->https://www.massdrop.com/buy/smsl-iq-portable-dac-amp..
cost only 109$ (88€ !!) but is shipped not before March 8, 2018 !!
the specs are looking great:
Dynamic range: 125 dB
Frequency response: 10 Hz–100 kHz
THD + N: 0.0003%
SNR: 118 dB
Bit depth: 16, 24, 32, 1 bit
Sampling rate: PCM (44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384, 705.6, 768 kHz); DSD64, DSD128, DSD256, DSD512
and according to this pictures/links it has 2 !! ES9018Q2C-chips onboard..
same with the Sabaj DA3->there also 2 !! ES9018Q2C..
they also said this Sabaj D3 with 2 Sabres sounds better than an Cambridge AudioDacmagic V2, what i really believe because i had an Cambridge Audio Dacmagic here and it was well manufactured but by far not such a high resolution as the ES9018K2M by example; on the first DacMagic there were Wolfson-chips in it->see review at the forum->LINK

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
according to their marketing, the M8A with one ES9028Q2M and a XMOS XU208 inside, is, as per their description, absolute DSD512/768khz-capable:
they say its primarily „solved“ by their custom-made/specialized XMOS XU208-firmware..
so if someone gets a hand on this firmware, rewrite it a little bit, everybody with a XMOS XU208-USB-bridge could eventually benefit from this and everyone with such a USB-Bridge could get DSD512/768khz..(with an ES9028Q2M).
but i guess we have to wait for that/its just only an idea 😉
