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 can't imagine that the amp (unless it's defective) is the problem. Most of the Musical Fidelity stuff is designed and advertised to drive difficult loads. That M6i is supposedly rated at 400 watts into 4 ohms and the poster has said over and over, it never gets warm. Seeing that the poster had the same problem with other amps makes me wonder if we will ever get to the bottom of this.

I saw that you had listed your system for sale. Did you get to the bottom of the problem or have you just given up?

While I hope that the new amp fixes the issue, I'm skeptical. I recently read in another thread a post by I think Audiokinesis that describes situations in speakers where the voice coil gets too hot and starts to limit the bass response of a speaker. When reading that, I instantly thought of this thread. If that's the case, then it's the speakers, not the amps that are causing the issue.
