"The only bragging rights would be for "how much was spent" which is at least objective, but does not say much else about the sound."
That would depend on your crowd. Those at AK typically take the opposite approach..., i.e., "how little was spent for the results obtained".
Unfortunately, it is impossible to accurately portray all aspects of the "results obtained" over the net and this requires attendance at the venue.
BUT, a good YouTube video can go a long way, and while you’ll never portray all the nuance, you will hear anomalies in the response and get a good idea of what the system is capable of, and you will know if it is garbage. Of course this assumes that you have a fairly neutral playback system on which to hear the videos or listen over good headphones and the video was well done.
