I've been playing with these 3 options of platter/arm relationship and have recorded some samples, listen back and am forming some impressions on the differences between a fully suspended AR and a hybrid with only platter suspended on springs.
Anyone have any experience or even some theoretical ruminations about why the original design is best (if you think it is) and why the other options sound as they do. At this point I am surprised that a suspended platter with a solid mounted arm (in my tests a separate armpod off table) sounds quite good. Tracking is not quite as good as stock it seems. As for solid platter and same solid mounted arm, I hear some stridency and lack of dynamics, although this might improve with a custom plinth
But anyone else use a hybrid arrangement (suspended platter with a solid/separate arm) with success? I see some doing a full solid mount as well as a solid arm with still suspended platter hybrid. (see link below)
According to the original design of course both platter and arm should be suspended on same surface so why does a hybrid arrangement work at all? and to my ears, sound quite good?
also, in this instance, lets assume we are just referring to sound and assume there is no need to isolate table from external speaker vibrations. I know that is a real world issue, but for the sake of discussion, i'd like to leave that out of the equationhttp://www.gigharboraudio.com/gha-custom-units/
