+2 Mike's products are top notch.
The bearing and platter upgrades were pretty dramatic when I installed mine. It's been almost a year now since I did the upgrades and I've been floored at the performance I'm getting, music has never been as enjoyable as its been the last year. I now no longer need to focus at all on turntable performance and I can focus completely on upgrades in other parts of my system.
