Toslink Survey / Please Participate


Digital interconnection, IMHO, has always held many myths.

When I first began delving into outboard D/As, jitterbugs, and transport combinations, very few component manufacturers (for some stupid reason) were actually providing coax RCAs (75ohm SPDIF). Interconnection, in many cases, was acheived through the use of Toslink.

Now most of here already know that I am quite an extreme advocator of balanced interconnection including, digital signal. I personally use AES/EBU on XLRs for my 2 channel system.

Out of necessity, I have had to hook up my home theater DVD player to HT receiver using the Toslink (Denon DVD 5000/Denon 3300). And after listening for an extended period of time, I have to ask, (because I obviously must be forgetting),....... Why was Toslink so bad? Why do many people say it sounds like crap?

The system sounds fine. Very natural and "undigital". I won't mention the Toslink cable manufacturer, but it is glass, and the cable costs $39.95. No "Break-in". No "cryo" no crap, just hook it up and go.

When you think about it, many issues associated with interconnection are negated. Balanced????? No Need. RFI, EMI ????? Trivial. Impedance mismatch????? None. Adverse environmental conditions????? Irrelevant. Overall, a very easy, inexpensive, and sonically acceptable interconnection. I don't know about 2 channel usage, but if this any indication, I'm sure it would yield acceptable results?

Can anyone comment? Is anyone still using it for 2 channel? Even if just out of necessity, or otherwise. Does anyone find Toslink unacceptable?

When I had the CI Audio Dac and PSU, it allowed for both toslink and rca inputs. I played around with different cables using the glass toslink from ebay against numerous other digital and analog rcas. I found the glass toslink to be middle of the pack. My budget digital cables ranging from D60 to wutever else I had at the time were inferior to toslink. The better cables were actually regular anlog cables I had at the time I think were Harmonic Tech Silways2 and Bogdan Princess to name a few. I've been using analog cables for digital even before this experiment which only further supported that good analog cables are better than digital cables. My theory is the cable with the most uniform impedance with the lowest resistance and capacitance is the better cable for digital or analog apps. Toslink is weaker in general, I think, because it goes through extra optical conversions which its quality is dependent on the quality of these converters. It's just one more variable that allows more chance for the signal to be mucked. When properly implemented, toslink can be good and cheap, but I think it lacks character compared to using rca connections. Ultimately, while were on this topic, I would want to explore other types of digital transmissions as well such as USB... when finances permit.
