one very obvious justification to charging more for the Wilson Benesch GMT One turntable is that the development was somewhat funded by UK Government. if WB had to amortize all that funding into the development expense the price would have been higher considering the projected volume.
surely Mr. Fremer/Absolute Sound were well aware of that.

we are not speaking about value here, that is purely a personal question. just the way a product is priced to allow development to proceed and for a reasonable return on the cost/risk.
