I have loved Ortofon SPU cartridges for a few years now, and I use them with a Pete Riggle Woody SPU tonearm. I like it because it sounds beautiful, and I think it sounds beautiful because of the choice of wood (Spanish Cedar, though he has an alternative as well, but I forget what it is), the type of bearing (a complex string bearing), the use of brass, and the fact that pretty much every parameter can be adjusted, most on the fly as you listen.
If you have the time to wait for Pete to build you an arm, you will be rewarded with an unusual thing that is visually beautiful, and far more importantly, musically accomplished. I couldn't be more pleased. You should check it out
