Colasblue - I might be wrong - someone will know! - but I think the 'Hydraulic Reference' used both types of feet. Certainly, there is one featured in the March Issue of Hi-Fi World which has round feet. On the other hand, a friend owns the same model but with 'arched, sprung' feet. As the company history notes, the Skeleton turntable was made from 1973 onwards in Ireland. The design went its own way in terms of arm, plinth, materials, feet and everything else for that matter! I think it is the coolest looking of all these wonderful turntables. As for performance, surely some of us own, and enjoy listening to ,'design icons' just because they are such rather than 'state of the art' soundwise. I reckon one would be hard put to find anything contemporary at £500 that comes anywhere near in terms of sheer style.
