I need to hook up a TOSLINK optical output to a DAC which only takes coaxial digital inputs. I looked around and found some converters, in particular, this one: http://www.ebay.com/itm/TOSlink-Optical-to-COAX-Coaxial-Digital-Audio-Converter-24bit-192K-sampling-rate-/221156873861, which claims that other cheaper converters only do up to 48kHz, and theirs can do up to 24/192kHz. On the other converters I cannot find their sample rate limit, so I'm not sure if this is true. Is there a difference in how high the sample rate can go for a converter like this?
Also any other recommendations for such converters are welcome, as I don't want any degradation in the conversion process (TOSLINK is already the worst affected by jitter I think). Thanks in advance!
