May I ask why you really need those specs? The tables are great at retrival and can't see you going wrong with either model. I would ad, if your going for the reference? Then look for the Amadeus.
Well Tempered Turntable Specifications
I'm considering getting a Well Tempered Record Player, mabye even the Reference Turntable, but I have been unable to find any specifications for wow and flutter or rumble. Were the specs ever published in the owner's manual? Did an independent lab ever measure a sample of this turntable? Google searches came up dry.
