3 points, in order of how strongly I feel about them:
1) Adhering to industry standards is exactly what you want in a product. It is not in any way "a good reason not to own" a product. Operating a TOSlink receiver out of spec is an awful idea, and will result in audibly worse sound. Apple avoided padding a spec sheet with an impressive stat, giving their consumers a more enjoyable product without their even knowing it. I'm happy to support practical engineering.
2) OP never asked for your opinion on whether he should upgrade the bitrate of his collection. Presumably, he already has 192 files and would like to play them. I'm confident, then, that he will consider your suggestion with the care with which it was offered.
3) the phrase "Yet another reason to not own a Mac" employs a silly use of confirmation bias, an argumentum ad populum fallacy, and (arguably) a split infinitive. It is a truly terrible sentence.
So I am glad to see that you believe in science. Perhaps we can restore your faith in grammar, logic, and comprehension next.
