Hi, Just went crazy and bought two Tim's from two TGP'ers (thanks neil99 and Garbanzoman). Noticed that they were different cosmetically. One is obviously older than the other because it looks different from the ones in online shop pics. They sound the same sonically to my amateur ears. Just wondering if anyone else has had the luxury of testing an older Tim vs a newer Tim. The circuits inside appear identical. What do you guys think?
