Dover: For whatever reason, cantilevered armboards appear to increase the bass volume and power, compared to non-cantilevered armboards. This is from my own experience, as well as from discussing these issues with other turntable designers.
Still, if I were to design an ultimate turntable, it would have a low-noise platter bearing, an ultra-rigid connection between platter bearing and tonearm pivot (ideally machined as one piece), a helluva lot of moment-inertia in the platter, and even greater moment-inertia in the plinth (which would be designed for low structural and cavity resonances).
The complete turntable would be integrated with a self-levelling air isolation platform, which would rest on a stone column that goes directly into the ground, without any contact with the floor of the listening room. Surrounding the turntable (but not contacting it) would be a double-wall acoustic shield, vacuum-evacuated between the walls to minimize energy transmission.
cheers, jonathan carr (using 60kg solid zinc plinth to connect platter to tonearm)
