Pulled the trigger on 2 reactor 600's

If you somehow can split the TOSlink into L and R and feed each speaker this signal you're good to go. I researched this some time ago and found that such splitting did not exist. You may find this today though. The simple workaround is to use the analog input of the Reactor (which will be digitised by the built in ADC) driven from the output of a DAC or preamp. L only to one speaker and R only to the other. This will most likely not sound as good as a direct digital signal, but you'll have stereo!
