This may have been answered before. I need to connect a Pioneer Elite DV-37 to a Denon AVR 5800. Whic gives better audio quality,a coaxial or an optical digital connection?

Thanks for the response

Farid

I've heard that it doesn't matter because it is a digital signal, but more people favor coax.

I have personally not been able to see a difference. However, digital coax cables are usually less expensive than optical. I've also heard that optical are more susceptible to damage from bending.

It seems that most folks go with coax, given the choice. My CD player manual lists Coax as preferable to Toslink.

The one advantage of an optical connection is that since the connection isn't electrical, there aren't any grounding problems. So if you get a hum problem when connecting two components (probably because they are plugged into different electrical circuits), an optical connection between the two may be the solution. Toslink though is the "cheapest" implementation of an optical link. ATT glass is a better optical link, but the most products don't include that option.

I think the cable manufacturers looking to sell more cable. Why all the telecom companies are changing from copper to fiber links? Bandwidth

I would say I have tried this comparison myself. I must admit I can hear a difference. I choose Coax.

Thanks for all who replied to my question.
I am convinced now that coaxial is the way to go.

Jerry, thanks for proving my point. While fiber optics are great for very long runs, such as used by telcom's, short runs such as we use in our home theater systems benefit more from the coaxial cables. I tried both with my DVD player into my Denon AVR-
3300 receiver, and there was no comparison.
The theoretical acceptable distances for S/PDIF is longer on coax then on optical.

Why is it called coaxial when it has the same old RCA connecter?

I use coax for the link between my Panasonic H1000 and Denon AVR-5800 because I've heard the technophiles prefer this. But one of the manuals (I can't remember which) said if you have the choice use Toslink.

Why the recommendation for Toslink?

Thanks

Help me again with this. If a digital signal is either a 1 or a 0, the signal gets to the DAC with proper timing, how could there be a difference?

Coax SPDIF has a higher theorhetical bandwidth than toslink.

Jerry et al,

ATT Glass fibre can carry higher bandwidth. IMO, that's the overall best solution out there. Now, how many consumer products use ATT Glass Fibre? Not many.

TOSLink uses plastic fibre, not Glass, and the connectors are cheesy. It's a shame really, because it has the potential of being superior to coax, but just doesn't deliver.

Regards,
