@OP Been having some computer problems so sorry for the late reply. Many thanks for your detailed and informative explanation.
How important is low W & F performance anyway?
I recently completed work on a direct drive motor controller for a turntable mfr with IMHO, rather impressive results (0.004% 2 sigma method, 0.002% RMS). In measuring other tables actual performance (vs published specs) I was shocked at the rave reviews two tables received that have rather lousy measured performance (but impressive specs). It made me wonder whether the goal of ultra low W&F performance was really necessary? I trust the measurements as they were verified by several methods and software tools and they correlated rather closely, yet the reviewers almost universally praise these tables. It made me wonder if the reviewers even know what they are hearing or listening for and not to put to fine a point on it, does it even matter?

@rauliruegas Everything you say reflects my experience too. Particularly what we can hear and not hear vs. specs. |
@faustuss There is no question concerning Bill’s credibility. It makes no difference whether you find his information useful or not. It certainly comports well with my experience and with what I have been learning since acquiring AnalogMagic. Take it for what it is worth. |
