FFT measurement:
From the meausrement, you can see this is a very good DAC and the distortion as well as noise floor is very low!

This DAC has all the good design inside. I believe Yamaha try to build one of the best sound DAC at the time back in 1990. This DAC give you the life in music but I feel the “Sss” sound is a bit over drive in high frequency. It use Sanya OS-con as the op-amp power supply decouple and I am not too sure if the high frequency glare is due to that! For the op-amp, I think Ti NE5532 may sound better as Yamaha switch to this brand after this model.
