Hey now, I think we all know that I invented the internet and that I DID NOT HAVE SEX WITH THAT WOMAN! Seriously though, He's just yanking your chain Rx8, he is actually a super nice guy but quite the smart aleck as well and he'll freely admit that!
ArtS is correct; from our testing we found that our good friend "the point of diminishing returns" shows up right around 20-22 a.w.g. or so. We have tried the different gauges(within reason) and found that it just doesn't get much better than 22 gauge but, if you have a seriously deep wallet, a mega buck system and a slight case of mental illness(in a good way of course) then maybe, maybe 20 a.w.g. But the cost just gets astronomical after that, or at least it does IMHO. I guess we all have our limits.
I do have to admit that rather than just offering an improvement in one area or another upgrading to the larger gauge improves the sound from bottom to top; more meat, more depth, more air etc. Like you all have discovered and said; "it's like Silkworms on steroids and is just more of everything". Now Rx8man my friend, whether going from 24 to 22 will be an improvement you consider worth the price of admission I cannot say. There will be an improvement you would be able to hear but, is it worth the cost in your case? That's hard to say and most likely only you can answer that one. Though I haven't personally had the priveledge of giving your system a listen I've heard that it is quite nice and you seem to be happy with it so, if I was you I'd stay right where I'm at, at least for now anyways.... :)
And just to clarify, I/KCI have actually been around since 1999 just not much of a presence(and I'm still not!! lol.).
Best to all,
John
