Scott Nixon offers a toslink input as an approximately $30 option to his NOS dacs. There is no switch between coaxial and optical, so you have to be careful to have just one input active.
Good battery powered Toslink optical DAC needed
Anyone know of one? I have checked the Ack-Industries and Scott Nixon Battery operated D/A converters but I have been unable to find one that has a Toslink input for digital signal. Is there any made? Thanks for the interest.
