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.

@cleeds on defining HTA:

The SME base allows for adjusting overhang, not HTA. Overhang and HTA are two different things.

I never implied they weren’t.

Overhang adjustment on any conventional radial tonearm will affect HTA - period.

Your image linked to the Audio Technica Headshell accurately displays how one must skew the zenith (HTA) in an slotted headshell when an adjustable HTA armbase such as supplied by SME is not available.

Awesome! The Ortofon SPUs are definitely on my TODO list. I've already got a few FR arms. 

Ditto 👍

Ortofon’s SPU Classic GM E MKII looks like my pick once they’re back in stock.

A SUT converts voltage into more voltage (Jason), at the expense of current, which is only one reason it would be nonsensical to drive a current driven MC section from a SUT.
