For my home theatre system, I was wondering what would be better, if there's going to be a difference, in using just an hdmi cable or using both hdmi and fiber optic. What would be the difference in using a M1000 monster hdmi cable alone compared to using just some slightly cheaper hdmi cable with a M1000 fiber optic cable. I'm still very new to hd sound and I'm not sure what the difference is because the hdmi cable still outputs hd sound, right? But, then I looked at the M1000 toslink and the price was considerably higher than the hdmi.....help?

Toslink doesn't support the HD audio formats, HDMI does. Otherwise, they will sound the same.

There's no need to buy expensive cables, which is just a waste of money. You can buy excellent cables at reasonable prices from forum sponsor monoprice.com.

HDMI would be preferable. It's a single cable for both audio and video and it supports lossless audio and multichannel PCM, both of which are beyond the capabilities of optical.

Optical or RCA digital is potentially better for audio than HDMI which tends to have much more jitter. Usually jitter is a non-issue with digital audio, regardless of what you read in the hi-fi magazines. But the jitter from HDMI audio can be ten times worse, bordering on being just barely audible.
