A bit of detective work So far i could match everybody correctly.

Okay, needed to make some changes to the PCB order (cut lines) - hopefully right now. Also increased the PCB to 10.

Update (29/12): Primary check went thru. PCBs are in production, Secondary check brought issues. Costs might be slightly higher as we need a 4 layer not 2 layer PCB

What changes were needed to make it work with JLC? I was curious and loaded the gerbers into their order page and I see the issue with the the cuts not showing up.

Quick question !

I see a lot of 100nf MLCC capacitors in the BOM for the build.
Is it necessary that they remain MLCC or could Wima Polys work for that as well? ( If so , what would you recommend , WIMA polys or TDK C0G MLCC? )
I have no idea if this is a silly question , my goal is to make this with as high quality components as i can

Thank you!

X7R 0.1 for power rails to amps.
(Polys would work there too. Experimental? But I doubt you'd really hear much of a difference -- if any at all.)

C0Gs across op amps in feedback.

For caps in signal path maybe Nichicon (Muse) BP or Panasonic.

No need to be too picky about poly caps in side chain filters.
