We are.

All the isolation you are getting is eliminating analog noise from your turntable. Picture if the turntable was in Ian's Anechoic chamber, feeding the preamp into your room. The noise floor outside the turntable would be almost nil.

Another way to think about it is this: the turntable produces a very small analog signal that has to travel from the cartridge to the phono preamp through the wiring. Noise can be introduced through electrical issues (so we ground) or through outside analog signals (vibrations from the platter, warped records, feedback from subwoofers ... all can have an effect, and all are noise, even infrasonic signals).

Expensive turntables go to great lengths to isolate from all these outside noise issues.
