Our group ordered a few RW600s, while most were fine, there was one unit that caused heat damage to the LP in the lead-in groove area.
Also, not sure whether this is the same case with Audio Desk / KL Audio, but a manual tug is required to start the LP turning with the RW600. I believe this has to do to the plastic lips (similar structure to the windshield wipers in cars) that hold the LP being too hard. It may get better when it soften with use.
