Absolute bulls***. Digital is digital, no matter what medium you transmit
it through. It's the same signal travelling through the medium - the only
difference being that with co-ax it's in an electrical form, whereas with
fibre, it's in the form of light pulses.
Optic fibre is totally immune to electrical interference, but transmission
distance can be dependant on the quality of fibre, terminations, etc. Both
are perfectly fine for everyday hi-fi/computer use.
AES/EBU, which is where S/PDIF came from, uses a twisted-pair balanced line
to send the same kind of information, but because of the noise immunity
characteristics of twisted-pair transmission lines, and the specification
requirements of the AES/EBU standard, the data can be transmitted over a
much greater distance than co-ax S/PDIF.
I really wish people wouldn't write such rubbish in books - I can't believe
people think it's possible for an optical connection to have inferior bass
response.
It's the same with these expensive interconnects and speaker cables -
interconnects are interconnects, no matter whether they cost 2 quid or 2000
quid, and the best speaker cable in the world is mains cable (2.5mm twin +
earth is ideal). That's another topic altogether...
Chrz,
