It was inevitable, but the subject of the thread has now become how a tonearm should be designed and built, rather than how a tonearms sounds. Unfortunately, we've done this new topic to death in previous threads. I don't expect my pointing this out to sober anyone up. Carry on.
I may as well throw in my own thoughts on the SATs. We all had to take them to get into a good college, so I don't see why the younger generation should be exempt. As for the SAT tonearms, they may be the finest sounding tonearms in the world (or not), but the prices are beyond irrational.
