Bass leaves after amp warms up?

I don't understand-after my Musical Fidelity M6i amp warms up for about an hour I notice the deep bass & kick drum aren't the same.
They sound less musical with loss of weight/depth.The notes are there but the moving of air have left.Sound is has much less impact and boreing.
I had the same problem with Bryston amp so there is no defect with amps nor with the rest of my equipment/
PSB Synchrony one speakers,AQ cables,Bryston CD Player.
My question has anyone heard similar & is there a plausable reason?

We're in the middle of a "cliff-hanger", hoping to find out what happens in the end. Like "who shot JR?".

I think the record is 10,582 posts on the MM vs MC cartridge thread and it's still climbing.

Is there any correlation for time of day? Maybe there is a difference in the power quality feed into your premise based on something else happening around your local grid? A long shot I know.

Since you have controlled for so many elements, the most likely culprit to suspect is YOU. I would set up a controlled blind test with an audiophile friend so you would listen to the system for 10-minutes on at least 4 separate occasions without knowing if the system was just turned on or if it had been on playing music for an hour or more. If this proves the effect is not imagined then I would sell all my equipment and move.
