That article doesn't offer anything new under the sun and as Rob points out, skips the most important aspect.
Totally agree about carts Rob. My $50 AT95E keeps up just fine with a ($400) expensive Ortofon Bronze. The Bronze only has a very subtle edge on the AT, if that. (By the way, I need to replace my AT95e due to a mishap with Magic Eraser).
In "audiophile" world (fantasy land) higher price equals better performance, but in the real application that is often not always true as you just pointed out.
