Intermittent bass


Can anyone pose a reasonable solution for a long existing problem?
I have excellent audio equipment
Bryston B135 integrated amp & matching cd player,PSB Synchrony II speakers + audioquest comet biwire speaker cable & Rega P5 TT/dynavector.
The problem I'm having is I get a really deep satisfying bass on all sources then at any given point the bass becomes dull & undefined.
I've checked & even replaced many of the above items but the problem persists
No one has been able to point me in the right direction..
Has anyone experienced a similar problem or guess why bass weight is changing?

Having checked the cartridge and connections, the only other thing I can think of is some kind of driver damage that escapes your view. It could be a small tear or rip that runs concentrically.

I hope it's an easy fix for you. Good luck.

All the best,
