The sound at large venues has always sucked. I stopped going to arena shows in the 90's for that reason. However,over the last few years I've decided to try a few for either my favorite bands or for group outings. I was really surprised at how the sound has improved since the bad old days. Fleetwood Mac, in particular, sounded great at Staples several years back and almost as good at the Hollywood Bowl a few months ago. Now, the bar was low, but I'm hearing improvement out there.
