I think tonearm matching for Ortofon SPU is very easy actually...It is best with Ortofon(RMA,RMG) arms or old SME and if you want even more exotic, you can use it with FR or Ikeda!
Ortofon SPU's outdated design?
Hi folks, I wonder if the Ortofon SPU's are in fact living fossils: they weight 30+ grams each! 40 years ago maybe it was a necessity but today? Average cartridge mass is nowadays between 8-12 grams. Headshell mass is usually between 9-12 grams. I know there are still fans of this carts but they are far from being "universally applicable", in fact tonearm/cartridge matching is more difficult than with the Denon 103. I wonder if the SPU's sound totally different if Ortofon would reduce their mass to 20+ grams (including integrated headshell).
