Hi Vunce,
Thanks, you will tell me your journey and opinion about the ayas you made, looking forward your pm review as the Ernsternst one btw. I am not active on the last Audial project as I was for the ones before.

AYA5 still is waiting for parts to be delivered. Will be a next winter project 🙂
I did some distortion trimming with my AD1862 and got some nice figures - brought it down by not far away from 20 db 🙃.

Yup, gathering parts for Aya5 will be challenging during these times…..
Ernest,
Did you populate the MSB trimming components and tune by ear?

Hi Vunce, yes I populated the MSB trimmer components but I trimmed it by measurement. I guess my ears would not good enough and I am not the most patient guy...
Yet sound is pretty good now, but it was before as well. Maybe cleaner, maybe not, probably yes ;-)
Today I ordered parts for Miro's USB and Spdif input card. Have 3 board available if there is interest =>PM me.

guys, I have found THT metal resistor from vishay in 5% ppm ... Make certainly no difference on a virtual oap ground but I liked to test the idea...ahaha 0.1% Z precision too, lol ! Crazy hobby, isn't it ?

Hi All,
I'm finally getting ready to start this project but having problems uploading Gerbers to JLCPCB. Seems to be something to do with the drilling layout (Gerbers alone load OK but of course no holes!)
Strangely - PSU2 loads just fine using Miro's file.
Any hints (or any spare boards for flipped or not flipped JLS version in the EU?) Warning: I have limited (but so far successful) experience with getting PCBs made...
Thanks in advance,
Mike
Info on blogspot from miro on first page "if jlcpcb viewer is not working, enter dimensions manually: 111 x 75 mm"
for the AD1862 pcb layout is there a library of commonly used footprints for diyaudio components, or do people typically make their own custom ones?
Friends, did anyone ordered AD1862 from Ali? I burned one chip and going to order there. Probably N-J grade.
You may be lucky or not... as chineese merchands are not always reliable there. I tried and one of the two had a broken leg inside...direct to the bin. They are second hands...
Hi Miro, I am strugging about the optical receiver for the USB/SPDIF board. Which one should we use? Is there one which fits the voltage and the footpring? BR, Ernst
Hi @ernesternest, sorry for later reply. You can use the mine, it is tested and it has very low jitter 😎

Ok, thanks, yet I would like to have one supporting the boards footprint!! Any chance?
Btw, I had the opportunity to compare a, in every aspect perfectly pimped, Soekris, vs. Topping E30, ADI2DAC and my MiroAD1862 in a nice setting with great amp and speakers.
AD1862 was detailed and relaxed - very natural sounding, enjoyable in every aspect.
Soekris was relaxed, good to listen to, yet not as detailed. Voices were more recessed and not as present as I am used to. Stage a bit more flattering and wider.
ADI2DAC was very detailed, good to listen to, but not as natural sounding as AD1862.
Topping E30, even it measures well and has got with the same chip as the RME DAC, fell short. Slightly artificial sounding, especially compared to the AD1862 (and Soekris). It sounds great with a headphone amp I own, but not in a big system - more specific - not in the big system, we were listening at (biggest vintage IEM monitors).
