OK, night 2 on the SlimSlide, silicone/Teflon grease applied to the bearing in the turntable..... either the new EP500 suddenly broke in (and I don't believe in driver break-in) or this made a huge difference in what is pumping out of these speakers. Forget wasting money on interconnects which cost a thousand bucks, or buying some electronic controller to make sure your 33 1/3 speed is within .0001% of speed rating. Get a tube of $7 grease. I am onto something here
