I was wondering which delivers better sound quality for a home theater system - digital optical cables or digital coaxial cables?

the sound quality is the same.

the signal is just being sent through a different medium. one is through electricity, and the other is through light.

it basically boils down to what your equipment allows. alot of htib limits you to only a few of each...and you'll have to live with that. most videogame systems have optical so save the coax for your cable box.

for long runs...use coaxial because the cable is made for longer runs. for short runs, you can still use coax (to save some money) or optical (if it makes you feel all warm and fuzzy inside).

Doesn't matter.

Like the previous post said. unless it's a particularly long run of cable, either choice will have the same quality.

FWIW, my Yamaha RX-V100 receiver, if it has multiple types of signals coming in from a single device, say a digital coax, an optical and analog as well, the Yamaha has a hierarchy if you will. If both digital and analog are present it will choose the digital signal. Now IF there were 2 digital signals from the same source, like ya had the digital coax and optical both hooked up, my receiver will choose the digital coax over the optical. This is just how my praticular model is preset.

My Yamaha RX-V793 receiver has the optical and digital coax input as well, but I only see one Digital coax input. Does the one cable serve as a left and right? The analogue inputs have both left and right.
Additionally, I'm using a HDMI cable between set top box and TV. Just trying to connect my TV audio to receiver. I assume I have to use receiver for volume vs. TV. I don't have an TV optical input on receiver only a DVD optical input. Thanks.

Yep. . .

As stated, digital is digital. Do you have a left and right optical?

Hmmmm

The only optical I have is DVD. Guess I'll us digital coax cables with my analogue inputs. Make sense?
Thanks.

Nope, two different animals. . .

Digital is digital, completely different from analog. And if you plug an analog output into a digital input, or visa versa you can damage equipment. Do not mix inputs. You cannot plug digital into analog or the other way.

Just some FYI on digital aduio.

Digital audio is 5.1, ALL the channels are encoded into the digital stream so only one connection is necessary.
HDMI the caries the digital audio along with the digital video. John
