Yes, you do have the Linn placed in the worst possible manner. It should never be on an equipment rack with other gear. It should always have it's own light rigid stand, preferably lower to the floor. I agree to get rid of the "God Awful Blobs" under the TT feet. Just placing the TT on a Sound Organisation TT stand, would make the Linn sound 10% better than it does now.
If you want to get a new TT, the Teres 255 will blow out any turntables that have thus far been mentioned. And it is lower cost than most of them too. Just for reference, I lived with a Linn LP12/Ittok/Karma for years, so I can give an accurate comparison to what you have. I have also heard most of all the other high end tables too. The Teres is a truly exceptional table, and is very good value for dollar.
