Shawn, my view is that any company(or individual DIYer, for that matter)that claims to be able to significantly "upgrade" audible performance with "quality" additions to an electronic component made by one of the major manufacturers can't be taken seriously. I did look at the Upgrade Company site and it appears to be the same old nonsense that I've seen from others trying to make a buck from tweaking a product whose performance is already excellent and is essentially untweakable. I note that at one point where a long list of positive attributes is given, the introductory phrase is "You can expect". At least that isn't a lie.
