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?

It's your ears, not the equipment. If you were to take a measurement, I'd bet you there'd be no change.

I frequently find, within the first 5-10 minutes, that I increase the volume about 3 dB. That's at an average level between 80-85 dB. It's a bit like your eyes; they adjust to brightness—your ears to sound pressure.

Could it be that the bass is tightening up as the amp(s) warm up and stabilize? Is it going from bloated to more lean with better definition?

Could it be that you are not hearing less bass just tighter bass as your entire system warms up ?
I prefer to let my system play for about an hour before I do any serious listening. It could be your room or placement of your speakers. Not your amp.
Just a thought.
