My second time owning one of these, I got it for a play because my Garrard 401 + AT 1503 MkI was coming back to me and I wanted a dedicated SPU to put on it. The reason for selecting the spherical version (having also previously owned the elliptical) is its musicality and oomph. It really is a boogie machine.
This one is in perfect order. It’s probably done 30 sides, but I have a lot of other cartridges and I need to fund-raise towards a new arm to replace the 12in Ikeda - hence its on the block. Offered at £360 including RMSD.
