@rauliruegas : Thanks for the discussion. I've learned a lot. I appreciate your patience with me. I am looking at the Technics SL-1200 G and GR. The prices are reasonable. Performance looks exemplary.
I come from a technical background - Optics, Electronics, Physics, so I take an analytical approach. Gotta have data to make a decision! I've learned here that I need to consider different, less technical means for evaluating my systems and components.
I will mount the Koetsu and the Shelter cartridges on the DP-57L, one at a time. And then give them a good listening evaluation.
I should figure out a way to quantify the table noise, especially wow and flutter. The wow and flutter test should be revealing.
