dpoud OPThey were never bass light, as they were even better than the Supex SD900/1000 in the bass, and they were considered to be bass masters and almost up there with Decca London Gold’s.
Koetsu black, lacking bass, does anyone know if the black cart is light in the bass?
Sorry if I’m repeating someone.
If all your alignments are right and your arm/cartridge mass resonant frequency is correct
Look at your arm height, is it "higher at the back" when playing a record, (arm not parallel to the record) this is a classic bass killer if it is. As your VTA is out the window.
