The DSP8000.2 still has a coax SPDIF input, I believe. So if all you want is to connect the TV then all you need to buy is an optical TOSLINK to RCA coax converter.

Make sure the TV outputs Stereo PCM instead of Bitstream. Basically, the TV has to decode any surround sound encoding and only send L/R stereo to the speakers.

If you have any sources that are not connected through the TV, that's the point where you would need to do something more.

Cheers!
