I think I made a mistake in observation. The M2tech Hiface 2 will probably require a new RCA digital cable so I will no longer need the Kimber Kable USB cable.
So the question now is : Will reverting to M2tech Hiface 2 + a new digital RCA cable connected to SPdif input of the DAC provide better sound from my PC than a High End USB cable connected to USB input of the DAC ?
