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:
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 😉 )
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)..

came here by chance to a new very interesting ES9038Q2M-forum->
some interesting pics/news on it, par example that the Green 1.06 has 7805 instead of 7808 on it and so on 😉 ->
by that, there is also a link to a 9038Pro-DAC (DACES9038PRO) designed by Andrea Ciuffoli/Quang Hao + a lot of interesting infos around the schematics of the sabre-chips->http://www.audiodesignguide.com/DACES9038PRO/
greets for now 😉

„The Hifime UDA38Pro utilises the ESS Sabre ES9038Pro DAC chip that has received a lot of attention and praised as the most important new DAC chip in ages…We have paired the ES9038Pro with OPA1622 output stage amplifier that can drive a wide range of loads including low and high impedance headphones and also line level loads like preamps and amplifiers… it can achieve up to 140dB !! dynamic range, -122 dB (0.00008%) total harmonic distortion plus noise (THD+N) in mono mode
Specs: (to come..)
