There are differing qualities of optical cable, yes. Glass cables are generally better than plastic cables (almost always true). ST optical connections are better than Toslink optical connections. (almost always true)
Coaxial RCA cables for digital are almost always better sounding than any optical cable. For audio (A Caveat). As in-I've never heard a optical cable outperform a coaxial connection.
the right inexpensive coaxial cable can sound better than some expensive ones. Try a few, even some well built cheap ones.
Your experience with the optical cable seems to be saying that something is likely amiss, as George is no dummy. His coaxial cable will be well built and sound good.
Your situation may be exactly true and right but it would be very much against the odds that the record of experience indicates as what is likely to happen..
