You have made your point. The others can read your posts and then use their own judgment. Needless to say that not all will agree with you. Personally, I'm not one to do much tweaking (along the lines of the mysterious products made by Shun Mook, etc). The only tweaking I employ is placing mass/weight on top of each of my speakers to help stabilize them and reduce cabinet vibration/resonance. To my ears, this tweak really helps to open them up. The other is using a clamping device of some sort on an LP when played (in my case it is a solid brass puck of about 1.5 lbs. with rubber on the underside). A clamp stabilizes the LP and dramatically reduces microvibrations. This tweak really does work (actually I wouldn't call this a tweak more than I would call it a necessity)...with analog, it is always best to use some form of LP clamping than none at all.
