They should charge more for it…

I think Einstein was referring to a hypothesis, not to audio gear. A hypothesis should be as simple as possible to explain the data, but not simpler.

The design concept of the GMT is reminiscent of an older very high end turntable that was made in the Pacific Northwest and now may be out of production.  (I can see it in my mind's eye, but I cannot recall the name.) A very powerful 3-phase AC synchronous motor is driven by three separate and discrete amplifiers, one amp per phase and controlled by precise upstream circuitry to maintain stable speed without the need for a separate servo mechanism. The bling that you guys object to is not appealing to me, either, but the idea and its execution appear to be first rate. I like that part.

There is the concept of diminishing returns.

I don't buy into diminishing returns. That assumes solid objective evaluation criteria, and also paints the picture of a nice clean horizontal asymptote where performance NEVER decreases as price increases infinitely to the right. Reality is a LOT more random than that.

@gkelly No disrespect but I don't think a $300k turntable is using a manufacturing formula for that price. The parts are the parts. Luxury items basically pull a price out of thin air as far as I can tell.

You need to really buy 3 of them just incase one breaks you have a back up

The Ultra high end seems to exist to make some of the other overpriced items look like a steal.
