I'm with Phild in that I have found digital cables, for whatever reason, to make a fairly significant difference in what I hear and I am no cable lover either. I'd much rather spend my $$$ on speakers, amps, etc. but the chain is only as strong as the weakest link, and at some point cables become significant--how much you want to spend on them is your call.
I tried toslink and found it to be soft and rolled off relative to coax, so I'd support the coax option for what it's worth. I'd also second Phild's recommendation of the Apogee Wyde Eye cable, which I've compared with much more expensive cables and found that it holds its own quite well and might be a nice first choice until you've found the higher-priced digital cable of your dreams. Best of luck.
