"Well, I've completed the upgrades, and I am very pleased! Was a very simple process (I do have a lot of experience doing stuff like this), and am listening to a Japanese pressing of Santana's album "Moonflower"- I love this album and know it backwards! The most obvious things I noticed is increased "air" around the instruments, and the bass is tighter and cleaner, with greater low frequency extension! My speakers are large transmission lines of my own design, and have truly subterranean bass, which is noticeably tighter and focused... It's not a totally different turntable, but I wouldn't expect or want that, but it has definitely elevated the performance of the table! I also installed a DC motor a couple of weeks ago, as the AC motor failed (...) Oh! Another thing about the TNG Spinner is the vastly superior spindle!!! The factory spindle is too short and too narrow! Yours fits snugly, and is a proper height!   Overall an excellent upgrade! Thanks Gus!   "
