Most of us HAVE posted demos, either here, on our own websites, or at some other arranger fora (you have some of mine already).

But possibly throwing down the gauntlet so aggressively isn't exactly the best way to encourage participation, perhaps...

And you will STILL not be able to judge what the 'board sounds like. Just how well, (or not!) each of us can play. You want to hear how good an arranger CAN sound, listen to the factory demos... Played by (usually) FAR better players than post here, with MUCH more time to make it sound it's best. Everything from there on is downwards, usually!

But if you want to hear whether we can back up our words, that info is mostly already out there (and widely known!).
