Parts are not bought at Aliexpress but at a distributor. You want original non recycled new ICs that have been treated ESD safe and not from the wet market of Wuhan.
Best is to use the BoM and order all necessary stuff in just 1 buy at Mouser, Farnell, Digikey, Reichelt etc.

Sorry to trouble you but I have one fundamental question - do I really need these 4.7 uF capacitors at the end of the dac signat path ? I can not hear any difference with or without them, Ok sure it has to do something with the rest of the chain. In may case I have a source/IFI stream.]/, dac. tube buffer /X 10/, three active filters /bass,mid,high/, three tube amps and then two pairs of three speaker ends.
Please advise when possible,
Thanks in advance
