SMSL AO200 Digital Amplifier with Infenion MA12070 I was quite fond of this amplifier and used it interchangeably with my main SANSUI amplifier, but recently it stopped outputting sound. I tried connecting the full balanced output of the SMSL DAC DO100PRO to this unit and the RCA unbalanced output to the SANSUI amplifier simultaneously. The sound suddenly stopped coming out partway through. Would be suitable for someone good at repairs or for parts. The items for sale are the main unit and a generic power cable. Please consider it as junk.
