Decided to try a SPU cartridge


I’ve been fascinated that the SPU (Stereo Pick-Up) cartridges, which was invented over 60yrs ago in 1958, still has loyal fans today. The SPU is reported to have a big, bold, exuberant and musically exciting character.

While researching, the best SPU cartridge may be the Ortofon SPU Century. I found one new at a greatly discounted price so I took the plunge.

Normally, it’s best to demo before purchasing. But because I’m going for sonic variety rather than improvement, the SPU’s sonic description and market longevity is enough for me to feel confident it’ll be a good experience. Besides, trying to track down a SPU demo in this Covid environment may be a pain.

In addition, I’ll probably purchase a Ortofon SPU Classic GM E MkII to experience the “original” SPU sound. Other SPUs I may try are Ortofon’s SPU Meister Silver GM MkII, SPU Synergy GM, SPU Royal GM MkII, SPU Wood A.

Next I’ll have to get a SPU tonearm. The usual suspects are Thomas Schick, Groovemaster II, and Ikeda. I wonder what’s the best SPU tonearm?

I suspect that tonearm cables upgrades won’t yield enough sonic improvements for SPUs.

Thanks for reminding me of the “Ortofon’s” SUT. I read that SPUs sound best with a SUT, but my Van Den Hul Grail SB is a “current” phono stage. Not sure if a SUT+”voltage” phono stage is significantly better.  I would ask the audio community, but I’m not optimistic that many have tried a SPU with a “current” phono stage. I do have a Lejonklou SLIPSIK 3 “voltage” phono stage I could use with the SUT though.

Groovemaster III is a pretty great value for new production. Of course vintage SME or Fidelity Research could be fun too...

 

 

I don’t think you can use an SUT with a current source phono stage. An SUT is a voltage-to-current converter. Regarding tone arms - a heavy arm like an FR or an Ikeda is a must for any SPU or low-compliance mc cartridge. Also SAEC arms!
