Thoughts about an upgrade to ES9038PRO->too expensive at present+DIY-audio-forum

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 😉 )
