Dear @wolfie62 : I owned at least two LOMC Ikeda cantilever-less designs and cartridges as the L-1000 by JVC/Victor and Dyna 13D that are designs with almost no cantilever as is the today LOMC AT 1000.
Very good experiences and not exactly the same kind of performance than the Decca non MC designs.
I think that on cartridges there is nothing really new but refinements on each design cartridge principles and designs as Lyra Etna SL makes that the MUSIC experiences in our system be a superior one to all those non-cantilever designs.
Cold be interesting to ask designers of the level of Lyra Mr. Carr what he think about on quality level performance.
Common sense tells that cantilever-less have and must be a huge improvement when a source of added distortions gone but a stand alone ( Ikeda ) stylus tip obviously has its own and different added distortions to what comes in the LP grooves due that the stylus tip was holded in some way in the " cartridge suspension " and after that comes the cartridge motor design.
Unfortunatelly in audio always exist trade-offs and our room/system will be as better as we choosed those trade-offs in each link of the room/system chain.
