@inna that is a nonsensical comparison. The task of a stylus retracing the groove is to all intents exactly the same as a microscope or scientific instrument and hence solutions that work for the latter will assist the former. This is one area at least where there is hard and obvious science and designers like Mark Dohman have integrated these approaches into their tables
you are right regarding subtraction however, for example subtraction of motor noise, as you can clearly see in the traces posted in my system ... 😉
and Geoff while I agree in principle I should warn that if you are thinking of using an active or spring based approach a rigid support is the way to go, lest the problem of conflicting spring Fr you referred to, or potentially (in the case of a Herzan) even feedback!
