@linnlp12 Thanks for the good words about the DD-40!
I measured all the tables I had a few months ago using an app that measures and reports RPM and WOW and Flutter. One can quibble about absolute accuracy, but comparisons among tables does indicate which tables have lower W&F.
The DD-40 came out # 3 of 4. The Technics SL-1200G and Denon DL-57L were the best. By a big margin, the worst table was my Acoustic Signature WOW XXL. Its W&F was about 5x worse than the Denon.and Technics (0.1% vs 0.02%) I've since sold this table.
And I really love the MA-505 arm. I have three and one long verrsion.
