Mine came with an optical cable in the box, it's just a bit of a optical fibre, not sure why they'd be expensive unless you believe hifi voodoohoodoo. I like my 0s and 1s to have a nice warm friendly tone.
The subwoofer is wireless though, but not Bluetooth. Possibly its sentient and does its own thing. BooBaBoom. Larrers is right about Bluetooth being the radio of lesser imps. It actually seems to work fine from my iPhone, but with a shiny new £1700 computer, it 's s t ill a bit s h it. Possibly I'm in the way but there doesn't seem to be enough of me to be radio opaque. Unless it's the Implant playing up. Mind you, I let a little bit of Chris Moyles into the system the other day. It probably fouled my speakers.
Our Samsung Bluray has started giving us cryptic messages in Korean. I've no idea what it's trying to tell me. Up pops a message box in Korean and then the screen slowly fades to black. I'm a bit scared. I keep meaning to take a picture so I can one of my Korean colleagues to translate. It could be an important message. It's following a bit of a trend, back in olden types I had a VCR player (toploader ftw) that had a very convoluted front panel with all manner of cryptic LEDs that would light up at odd times. I think it was trying to communicate but I never found out what. God, I miss tracking control. Ever was better with tracking control.
