I like the sound of the MU90 more than the later models, but I was still a little dissatisfied, so I modified it.

have a listen:)

I also made my own USB Bluetooth DACs and Amps, (even the sound of vintage CD players are not enough for me)
Speakers are Pioneer from the 80s
have a listen 😀

No, it's not just recap, I optimized the parameters of each capacitor, the sound improvement is greater than changing opamp or dac chips
