I have not used toslink but have heard -- from those who have used it and are credible -- that it is important to use glass rather than other materials. FWIW.
Why are optical cables jitter prone?
A friend of mine convinced me to purchase an electrical (RCA jack) digital cable for the home theater. He said that even though optical looks neat, it is extremely succeptible to jitter. I thought both kinds were. But, low and behold, I switched to the RCA type and my bass immediately got louder and tighter. Does anyone have a short and sweet explanation as to why? Thanks.
