A good friend of mine developed the theory that we need to follow the ideas of Copernicus understanding the importance of a tonearm in the analogue playback system.
Using his words “For thousands of years it was believed that the earth was the centre of the solar system and that the sun revolved around it. Before telescopes existed, Copernicus proposed that it was the earth in fact, that revolved around the sun.
The tonearm is now the centre of this ‘Turntable System’ and is the most important element. It must be rigidly held on a base which is perfectly flat, non-magnetic and relatively immune to structure-borne and air-borne feedback. This base must ideally have no contact with mechanical or electrical interference and must under no circumstances, move or deflect in any manner.
This base should ideally have no contact with the drive mechanism of the platter or the plinth, sub-platter, belt, gears, idler-wheels etc.
this base should be an island”
This copernican view of a turntable system favours separate arm pods. While some audiophiles developed their own armpods I was going for a rare tonearm stand, the TOHO arm base TH-80 – a wonderful piece of machinery building of the golden Japan Analog Times…
We may not forget including here different opinions on the matter like that the tonearm/cartridge do form a mechanic-dynamic system and the two together with the plinth/underground do form a mechanic system. The discussion may have not ended yet…
Furtheron I developed my own AudioCirc design and built several arm pods serving my many tonearms. here is one of the units:
