I used to own a regular 308 and a 308SX, but not at the same time, if memory serves me well. All these suffixes of N, L, SX are confusing. But I remember it visually and the counterweight is heavier with a bigger diameter chunk at the back. I think they were originally for heavy cartridges like SPU. Not so sure, just a hunch. All SAEC arms have amazing bearings. When you pull the armwand, there's no slop or chatter whatsoever in the bearings. None. That's a great start for a quiet system.
However, it had a rather sterile sound so I didn't have much luck with the sound but back then I didn't know what I was doing so I cannot be fair and that was probably 20 years ago. It was purchased for only $200 at the time. The design was the Japanese's answer to the SME. Build quality is better than a typical SME 3009 and much better bearings. The one nitpicking is that I prefer SME's way of doing antiskating because it's independent from the vertical movement. The SAEC uses a rod attached to the counterweight post and that might hinder vertical movement.
I would give it another shot, if I acquire one.
