The 'deceptive' part is the IS in the sentence form 'x is P'(aka the subject -predicate).But we want a tonearm which satisfy many conditions and this assume a list of properties not just one. Besides 'the best' imply comparison between how many tonearms?: 3, 4, or...
What we get is actually: John thinks, believes, is convinced that,etc. that the tonearm A is better than the other he ever owned. Assuming that most of us owned, say,
3 tonearms this 'best quality' become a very hazy qualification.
