Wayne: thanks for the advice, ill move the PS around and see if i notice any improvement. Excellent suggestion on footers. Never thought footers would matter on a PS. Good excuse to order some more isonodes or herbies.
As for what i was hearing with the cloth, it was a slight reduction in overall noise and grunge. Most notable on the high end. Just seemed to reduce some grunge. There may have been more bass but hard to tell if this was due to a reduction of noise in general, music selections last nite or just a decent bottle of belgian ale.
