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?

The weight on the cartridge could be the culprit. Too lihht may rob you of bass. It will show more on loud passages and possibly certain points on the album due to tracking.
