Since everyone hears differently, has different sonic values and priorities ( bass extension, soundstaging etc. ) and is listening in an unfamiliar room ( at shows) , I would expect a difference of opionion as to "best of show".
My biggest concern is the seemingly increasing loss of any idea of value for money . The law of diminishing returns kicks in quite rapidly and yet reviewers and audio buffs like us use words like *major*, *couldn't believe the difference*,* discover my music collection all over again* to identify noticeable but often rather subtle changes.
Now where that line of very diminishing returns kicks in can be a very individual choice but I tend to think it's much lower than many of us want to admit.
