For many years I have been enjoying the WTA 'Black' arm This arm was made to upgrade the regular WT arm of the time...mid 90's. It features a once piece arm tube/headshell, Van Den Hul crystal internal wiring and a black anodized arm tube. i like the arm a lot, but sometimes question its abilities in the very low bass. Also, I wonder how it would work, if at all, with a heavier cartridge..like the Benz LPS MR. Anyone else have any experience with this arm?
