I have no direct experience with SS, other than a cartridge repair they did for me. They did great work, and were a pleasure to deal with. SS and VPI arms are supposed to be very synergistic, so I doubt a there is a mismatch. I have heard the DV 17D3 and 20X2, Low output cartridges. I heard them on different occasions, and on different setups, so not a fair comparison. I preferred the 20X. It sounded more even handed, had more weight, and never offended.
