I've owned my LP12 for over 20 yrs! When the Keel was 1st introduced, the Linn dealer (who regularly tuned mine up!) in Atlanta did a demo between a keel'd and an un-keeled for a group of us. It was the single-most demo that ever made me doubt my hearing acuity. The difference was so slight, certainly not worth 4 digits, let alone 5!
