Is there a dac that will take the two rca cables from my tablet (currently streaming ) and two from the cd player for a total of four inputs and have two rca out to the aux of my vintage receiver? I've seen a couple British models but have yet to find one here in the US. So basically have everything run through a dac. Will I have to buy two separate dacs? I'll run pro audio to bypass the internal dac on the Samsung tablet. I'm curious on how much this will improve the sound. Thanks. Btw I DON'T need a headphone option as I never listen to music that way in the room.
