In vintage turntables, I prefer spring suspension augmented by the turntable being placed on rubber isolation feet. My Technics SL-1700mk2, which benefits from a non-resonant substructure which is spring-suspended, has its feet upgraded to the rubber-isolation feet from the brutish SL-1200mk2, which has no suspension whatsoever. The result is great. For my application anyways....
Just an observation here, but????????
Is it me or has anyone else noticed the change in turntables designs from with sub chassis to without? Is there any manufacturing or acoustical reasoning behind this?
