Considerable discussion? The only time I've heard that was from Qvortrup in context of his tt which is basically a mid to lower midfi British design. The questions you should ask is to define high mass, the overall design, what type of energy, where and how it's stored, which turntables he's compared it to and how are they bad? A simple claim isn't considerable discussion!There is considerable discussion around the using of very high mass being detrimental due to energy storage in the platter...seems many on WBF don't take much stock in this issue.
They couldn't be any more different in concept and design, nothing in common between the two.The Horning SATI TT looks very similar in design and comes from
Denmark I believe. Maybe try a demo with that one…I think Audiophile Bill has one…
Even with 50kg you're pushing the limits of an inverted bearing. AS, AF and MS have air floating platters technically none of them have air bearings.I think they said they tried heavier but preferred 50kg. Does the AS have an air bearing?
