Good general guidance from Ron.
I'd add this serious warning, that breakup you're getting on HF's is a result of a mistracing stylus. If it's on just a handful of records it's probably damage from a previous owner's rig. But if it's on many or most records than it's your rig and you should STOP PLAYING YOUR RECORDS. You're damaging them permanently.
Fixing that problem is job one. Record cleaning, stylus cleaning, higher VTF or a better cartridge are all possible fixes to explore.
