I bought a well made Toslink cable for my MD decks recently and made a quick comparison of the digital input recorded disc to the analog recorded version of the same material on NOS Sony ES minidiscs . The analog recording is lower in volume with less highs at the top and a rounder warmer bass at the low end . I'm going to reset the analog volume level higher and re-do the analog recording to recheck . Robert Harley, the author of a book on High End Audio states that the order of recording quality on digital recorders like MD is best on a Coaxial input and the second best option is the analog . He said the Toislink optical connectors aren't very good and appear to have errors resulting in some missing information being transmitted . I don't know if he was referring to earlier versions or in general . I never used the cheap skinny Toslink cable Sony provides with the deck accessories and always replace the cheap RCA interconnects given away free with new stereo gear with better made ones . Any thoughts on this topic ? Any body willing to share their preferences ? tx
