Sounds like I was wrong in assuming the app measure EMI and not magnetic field strength, as "Gauss" is a unit of magnetism (but it might also be a unit of measure for EMI; I need to check). I have no evidence that magnetics is any problem with L07D or SP10 Mk3, the latter of which has a humongous magnet and a very powerful motor. Anything ferrous will block or absorb magnetic forces. When you did your measurements, was the TT101 fully assembled and running? Did you compare with and without the "pants"? Possibly blocking magnetic field from the transformer or motor is the primary or a secondary function of the pants, since we do know they are ferrous. ("Old Ironpants.")
The discussion of the awesome Final Audio tts and their relatives brings to mind another audio conundrum. Does a tt need a massive heavy platter to reproduce extreme low bass? Halcro may have an opinion on this, since he is running his TT101, which has one of the lightest platters I have seen on a TOTL DD tt, vs the Raven tt, which has a typical massive platter associated with the high end belt-drive tts. Henry, do you perceive a difference in bass reproduction between the Raven and the TT101? If so, in favor of which tt? Thanks.
