hey guys, trying to figure out the best way to connect my logitech z906 to my onboard sound (asus m4n98td).
The only outputs on the mobo are optical s/pdif, coaxial s/pdif, and 'hd audio' 1/8" (headphone type plug) for 7.1.
I'm inclined to use optical toslink for reliability as i hear coaxial doesnt have any major advantages, but with the limitations of s/pdif, would analogue hd audio 1/8th plugs be betterer?

Probably optical. Since its only one cable. But, have you got a cable?

i have one on order. I dont mind using more than one cable, but would the analogue hd audio cables sound better or have any advantages over s/pdif?

I can't imagine it would matter with that speaker setup.

On my system there was a very noticeable difference between optical & coaxial, No idea about HD cables though.

This may help

http://en.wikipedia.org/wiki/Toslink

Or this

http://en.wikipedia.org/wiki/S/PDIF

I dont have digital myself (I do have a soundcard with analog / digital in / out), and the toslink cable. But I dont think there are any 64 bit drivers for it. Or I would probably install it. It would probably be better than the onboard sound

I dont know alot about it, but believe digital sound is better definition and range than analogue, if you can go digital, I would go for it. Coaxial or fibre.

metla, are you saying optical was better than coaxial or vice versa?

from Wiki...


Signals transmitted over consumer-grade TOSLINK connections are identical in content to those transmitted over coaxial S/PDIF connectors

I figured that was the case, though it does make me wonder why my system sounds better using the optical....

The optical was better, I was running them both for an instant comparison.

In an earlier thread someone mention optical was no good for HD audio as it couldn't handle the bandwidth and downgraded the signal.

They also said that only HDMI cables would carry the full HD audio.....

yea i heard that too, but with the analogue HD audio 1/8th plug, it could be better than optical because it is hd and optical is not hd...?

Connect it once you get the cable. And see which one sounds better

but the analogue hd audio is 4 cables, which i dont really want to buy unless i know it will be better than toslink
