I think I understand what you are looking to do, and I personally think banana plugs, or raw screw-downs would be the way to go on the "audience" facing connections.
A few years back I did a lot of research on cables and brands, and I do think there is a difference in the brands and quality (not wanting to get that old battle raging again). I have some slight hearing problems to begin with, so noticable audio differences were ALWAYS minimal to me at best, when testing different wiring.
However, I think the quality is where the difference (for me) was found. Better cables seem to be more managable, tougher, less likely to oxidize, and have a better fit and finish to them. I've used Vampire Wire for ages, and (as of a few years ago) you can order custom lengths of any gauge, and have them preterminated with the type of ends you want to use. You may want to give them a shot...I've always been pleased with their quality, and everyone I've pointed in their direction has been pleased to.
