“Subjective preferences about audio components and sound and music are not susceptible of any kind of objective right and objective wrong; almost nothing in this hobby is objectively correct or objectively incorrect.”
If the concern is the second clause, then I am happy to amend it as follows:
Subjective preferences about audio components and sound and music are not susceptible of any kind of objective right and objective wrong; with regard to subjective preferences almost nothing in this hobby is objectively correct or objectively incorrect.
I think both statements are apt and clear but there is no need for the clause after the semi-colon in either sentence.
Introducing the notion of objective right and objective wrong could be a bit messy due to a bit of fuzziness in the notion of 'objective', and the implicit judgemental character of 'right' and 'wrong. (We're not talking about morality.) It strikes me as simpler to talk about 'what is the case' and 'what is not the case' and perhaps simpler yet 'what is fact'. Here, rather than use right or wrong, could you accept factually correct and factually incorrect?
Or ... some way verbally to distinquish between preferences, opinions, and fact in one's writing. Clarity is incumbent on the writer; careful reading is the obligation of the reader particularly wrt issuing a response.
It should be straightforward to come to some agreement on what is fact, what is the case, and if it's not then discussion can stay in the realm of evidence without introducing opinion and preference. Sure - we can disagree on what is or is not the case, but we should agree that what we are discussing is (theoretically) determinable. This might be called rationality. In the case of the subjective we should not expect agreement.
I don't think there is any harm in someone stating 'in my opinion' or 'imo', etc. even if it is obvious or redundant or we might get tired of reading it. Again, be clear, don't presume.
What really is at issue, imo, is the tendency (of some) to make statements in a way that
declares preference as if it were fact.
Edit: After reading one of David's posts upstream I should amend what I said about right and wrong. There certainly can be the right way to do something or the wrong way. (One usually leads to success, the other does not.) The right impedance for this phono stage, etc. ... But there are not right and wrong facts.
