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?

If you had the same problem with the Bryston amp it's very unlikely a power amp issue. Sounds like a power issue. Either line/conditioner or pc. Have you tried switching power cords? Maybe a defective conditioner? Voltage flucuation?

Simply would like to know if anyone has experiencd even a noticable change of music being reproduced from one time to another?
It seems the symptoms I hear have no precident..
Which bothers me the most I think
I've looked on line + spoken to all the manfacutures of my equipment..Most won't even accept my calls any longer.

Have you tried different speakers, as Kijanki thought you might have? And if so, did the same phenomenon occur with them?

I'm still suspicious of the possibility that the performance of your speakers is changing after they have been playing music for the hour.
