Right Frank, I suppose that was also the reason that Enid Lumley finally gave up and dissapeared from the high end. She did such a perfect dissapearing act, that nobody seems to know about here whereabouts and what she is up to. As you say, her hearing must have been incredible. Not only could she hear differences in sound with different VTAs measured almost in my, she also maintained ( rightly probably to HER ears ) that you would have to find the right spot of an LP in placing it on the turntable and that every LP had a sweet spot within its 360 degrees, where you had to put your cartridge on to start playing it, for best sound.
