Does my iMac support 5.1 Digital Speakers?

[iBunny]

?

Or am I stuck with analog?

It supports optical digital out, which means it'll support the speakers - as long as they or the receiver into which they are plugged support optical in.

Yes, the combination headphone/optical port will run 5.1 sound.

I started this thread awhile back, maybe it'll help you too.
