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.

You should be able to use a SUT into the MM section of the Grail.

The autoload sensing pertains to the MC input stage only.

I suspect for a SPU, the sonic differences between these arms are small.

No.

Also, just to reiterate, if you want to play with SUT's, you can use them with the MM input on your Grail phono.

This whole HTA discussion highlights that if you want accurate alignment, you should only buy

- cartridges with conical/spherical tips

or

- cartridges that have a nude mounted square shank diamond and the cantilever has been laser cut.

If you are spending $5-10k on a cartridge, spend another $100 to have it independently inspected by a cartridge retipper. I have seen several $5-10k cartridges with styli mounted askew/cantilevers mounted incorrectly ( rotated ).
