Brand New Vinyl Static and Pops

All my older vinyl sound pretty horrendous, so I avoid playing them.

My new LP's all sounded great up to a few days ago.

The static is minor compared to the flubbing noise which is sever.  Not playable.

What is a flubbing noise? Rumble?

What is yout TT and Phono Section. 

Is there a subsonic filter on your Phono pre/section?

yes sort of a rumbling sound with the sound muffled. muffled is a better description.

I have a Technics 1500C TT connected to an old Denon receiver.

Nothing has changed.  Not sure what is happening. Odd.
