I've been looking at the Tiger-Paw Tranquility as an upgrade option for my LP12. It uses magnetic force to reduce the load on the bearing without totally removing it. The design seems to me a good compromise of still keeping the mechanical bearing, but minimising the force going through it. I've read a couple of online opinions on the Tranquility and it seems to be positive. Anyone any thoughts on the Tranquility, or experience of using it?
