Thanks, Mike.
Macrojack's statement does not quite make the claim that Audiofeil wants to debunk, but it is likely to be the one he had in mind. The real question is why is Audiofeil so angry?
As regards vintage tonearms, whatever anyone tells you is just his or her opinion. A few years ago, most of us were convinced that vintage idler- and direct-drive turntables, and even the ideas behind these drive mechanisms, were inferior and passe'. My feelings are quite different now. (And of course you were ahead of the game with your Rockport table.) Likewise, I personally have had an epiphany as regards the merits of vintage MM and MI cartridges. (Pause while Audiofeil cranks up another insult....) So I am keeping an open mind on tonearms. While the engineering of many of them may seem dated, the quality of construction is often very high, higher than that of some of the current crop. I haven't heard them all, but think of the vintage SME, Ortofon, Lustre, Stax, SEAC, and older Dynavector products, as well as the Technics vintage arms.
