If this thread isn't the place, then the board members or president should start an email chain to address this issue. I think it's ok; we're not outing a serial killer or anything...
Every single meeting has this issue; unless you are willing to stay until 11 pm on a Friday night, after most have left, there is no way to hear a club member's system.
For starters, maybe a Saturday afternoon meeting, where it could go an hour or two longer, and separate into those who want to socialize, and those who would like to actually listen to a club member's system. Early for the social crowd, later for the audio enthusiasts. I just don't see many club members having to skip Saturdays for a tee-ball game; we're a pretty (ahem), mature bunch.
I think part of the problem is that everyone feels they have the right approach to sonic nirvana, and listening to the host's system will simply verify that notion. Therefore, why bother listening.
End of ramble.
