Let's see some test reports from a certified lab. And that's not 6 moons or The Absolute Sound either!
For folks like yourself who require such things as test reports from a certified lab, EE backgground, EE theory, etc, I can understand that you would not think positively of these kinds of upgrades. My old dealer (in business in Phoenix for 20 years and then forced to close down a couple of years ago), sold all sorts of gear from Arcam, Pass Labs, Cary, YBA, Cambridge, etc, but he also did some mods on my Cambridge CD player. He doesn't have a EE background and didn't have any foundation of established EE theory; however, his mods sounded great. At least, I knew him, and knew that I could go see him face to face, if there was any issue. With David and The Upgrade Company, I was a little worried at first, but the upgrade definitely had improved the performance, so I was happy. And, I've been happy ever since, with the several upgrades he's done to other pieces of equipment. For me and my preferences, it's been a good direction to go.
