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?

I've been having a similar problem, not only do I lose bass but the overall clarity drops. Sometimes my system sounds awesome other times not so much.
I believe I just found the problem, I wasn't sure if it was the amp or pre-amp so I ran the I/c directly from my Oppo to my amp. Flat sound no bass so it's the amp not pre. I wanted more volume so I reached around back & changed the input sensitivity switch, bass returned although the highs were a bit harsh. I moved the switch back & forth a few times & put it back where it was & it sounds great. Hopefully that's it & it will stay that way.
It's a McIntosh MC7270

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