I was literally about to write this same comment, more or less, so will just upvote you instead. I really truly want to objectively know whether the £X,000 I might commit to an "upgrade" is actually an upgrade, even if "objectively" in fact means just "subjectively by a clear majority of a large ish sample". Obviously any serious purchase needs a personal listening audition first, but I want to know I'm not wasting time by even shortlisting certain candidates. Otherwise it's - where to even start from literally hundreds of amps and speakers?
