@Juan_A_Sanchez I’d be surprised if the chip in the Audio Expansion Card is either of those. Based on NRP’s posted from quite a while ago (linked below), it’s probably a USB DAC similar to the one he links. FWIW, I really like the Audio Expansion Card. I sounds markedly better than the tempo chip in my 11th gen FW. Even my 80 Ohm DT770 Pro headphones sound quite good, and there’s loads of headroom for me to turn the volume up as high as I like.
I cracked open my audio expansion card, but I didn’t see any part numbers that looked easily google-able. I also couldn’t figure out how to make Windows tell me what chip is in side. I’d be willing to try again on either of those if you have a suggestion of how to find the chip info.
