Connect Panasonic SCHT880 to Sky+ with phonos or new system ?

[SGH42]

I have a Panasonic SHCT880 but there is no optical connection for Sky+.
I can connect via 2 audio leads but would I get better sound by going for a new system with optical input so I would get 5.1 ? If so what would people recommend or would I be better of waiting till blu-ray systems come in ?

Thanks
Steve

Do you not only get 5.1 on certain Sky Movies, not all the output? If that is the case, I would only bother if that is something you are desperate for. You are going to get very little difference otherwise.

If that is the case then yes I'll be better off waiting for blu-ray me thinks
