Today, I gave my late wife’s stereo receiver and cd changer to my daughter. The receiver is a Marantz stereo receiver from the early 2010s, works perfectly, no digital inputs. She has a TV with no analog sound outputs, just a solitary Toslink outlet. So I now need a small cheap DAC to convert her Toslink to a usable analog signal. I want it as simple as possible, no volume control, just a simple box. Any suggestions ??
