What do the caps cost them?
So @jetter are you suggesting ARC should just provide the upgrades for the cost of the parts? That’s just stupid and is a recipe for going out of business for any audio manufacturer. Plus, having anyone else do the work, assuming they could because it’s more than just soldering in some new caps, will void the warranty. Did you even consider that? Your thoughts are, frankly, ignorant and short sighted. But u do u and see how that flies.
