I am sure even a half good sound engineer can cope with the difference between a full hall and an empty hall though. And if that were the case it would happen at every concert everywhere. i know, why don't they invite us all to the sound check - how cool would that be? :-) You may have a point there for a bit of leverage to getting in on the afternoon!
But Guy keeps telling us they're so, so good that now they don't even need to do soundchecks and that's why the sound is so great!

Soundwise, the RAH is a nightmare.
To get a real good sound there it is lot of work as the hall is not designed for amplified music.
Beside it can be excellent to one area and very bad a few meters away. There are some box that I won't definitively go back in again.
I had the opportunity to chat with a singer that performed on that stage. She explained that the echo from the back is 2-4 second delayed so it is very difficult for vocal performer to properly work in such condition. Myself in 2001 seated on the 2nd tiers box I saw MK drummer hit his tom and but the sound was coming late.
Using IEM for musician is a huge improvement because they cut from the disturbing accoustic artefac of the venue.
