Best ever tweak...learned in the 90’s......Play the 1st. track of Any CD...then take it out and spray the silver side with ArmorAll..wipe it clean and replay that 1 st. track again....Noticably More dynamic...more mussical.....about a 20% inprovement in SQ. You’ve got more info coming back to the laser reader. Fill in the pits for a more focused sound. Go ahead, I’ve been doing this for many years...IT WORKS!
