FX-AUDIO FX-01J Portable DAC

I accept requests for price reductions and combined purchases.
(Approval may not be possible depending on the price.)

This is a USB DAC that has been confirmed to produce sound when connected to a computer.
However, I do not have any high-resolution audio files, so I have not confirmed whether the 88.2k indicator lamp lights up.
There are switches labeled FIR and IIR, but I couldn't hear any difference in sound quality when switching between them. Therefore, I cannot confirm whether the switching function works.

I will include two yellow RCA cables. They are 1.5m long.
Although yellow cables are originally used for video, they can be used as a substitute for red and white cables.
