i just received my Acmee MF-01 along with a couple of Walnut V2s's.
I opened up the walnut to op amp roll them to an OPA 627 on a browndog and the LME49720NA but the op amp looks soldered and not removeable like on the Z3.
I though the Walnut were designed for op amp rolling like the zishans? Did I get the wrong model?
Also the Acmee doesn't seem to like any of my cards even though they are all formatted in FAT32. I can't find any specs on the card reader but i assumed like with all the other chifi DAPs you needed FAT32. It's just a #@ and 64 GB card from sandisk. Any idea what I'm doing wrong? I really want to give a listen to this device with the Muse02
Works perfectly with FAT32, I use a 128GB card without problems. But remember you can only use one folder level!
