Funny that you just mentioned this platter! I recently saw this item at Elusive Disc, and my first thought was "Holy S**t, $2000- for a special PLATTER?
Don't get me wrong, but I think that we Audiophiles are Super Tweak Freaks [myself included], as we try to eke that last little drop of performance from our rigs! Some people, even other audiophiles, will say that this is nuts; myself, I'm not going to comment on someone else's passion, cost, or method for his "pursuit of happiness". Actually, in this mass marketed, injection molded plastic, disposable society, passion and dedication are desirable qualities, even if others see them as quirks or shear lunacy!
Unfortunately, unlike tweaking a fast car, fidelity improvements are not scientifically measurable. But rather, beauty is in the eye of the beholder.
So, what's the going price tag for happiness these days, anyway?
