I do accept that.
I have evidence to suggest that electromagnetic coupling may be a strong contributing factor.
If true, then your aluminium base, or a wooden base, plastic base, concrete base, granite base, even no base, is better than the steel (ferrous) base that they put there. This would apply not just to the CD94.
I have nothing yet that explains how weight or rigidity would effect the sound, but I am looking.
