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?

THird option would be to try speakers that are an easier load to drive with existing amp.

But I think you will practically attain very high levels of performance sooner by using a dedicated amp better suited to bring out the best in the PSBs. Use the current MF integrated as a pre-amp only then, as AL suggested.

Let's see what the SPL says. We'll all be waiting to hear.....

Fishing, You've had so much good advice here, I believe the solution lies within. I don't think you should make any major decisions (like new speakers) until you've measured the SPL.
On the subject of amps into PCs, just FYI, my Sunfire manual states "do not plug the amp into a power conditioner."
