What do you mean by electrostatic cleaner. Are you wet cleaning them with a proper automatic cleaner or a using an ultrasonic cleaner? Do you clean your stylus properly and how? I use a Nessie Draabe Vinylcleaner pro to clean my records with fantastic results. The only way to make your stylus sound like new is using an ultrasonic cleaner like the flux sonic. Other methods don‘t even come close. Maybe you also have to much downforce on your cartridge. There‘s a sweet spot that‘s not always the same as the manufacturer recommends. You just have to test and find out for yourself. Maybe you should see a doctor and get some earwax removed. You never know :-)

What headphones are you listening on? I have Stax earspeakers at home and have none of this distortion or panning you mention. His mastering of The Cars - The Cars album is phenomenal. Maybe you should clean your records properly first. Or maybe your cartridge setup is wrong?Some more information on gear would be useful.

I got two of these things for free with my internet subscription. One of the worst freebies I have ever been given.
