Yes, I had one. It is a moving-iron design, with a vintage going all the way to the 1960s, and revisions to the present time. It is an excellent tracker, but the 881s (mm) is better. The sound is very clean and neutral, but the 881s is recognizably clearer on AB comparisons. In my mind, the 881s is recognizably better in all respects, including sound, and higher output...meaning lower noise ratio. I guess this model still sells because it has a strong following from about 40 years ago. The complete 680 series have the same internal design, and all the stylii in the 680 series are interchangeable with this body. Nice to know, if you want to interchange with a more rugged stylus for special purposes. Very good performance to cost ratio.
