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?

This may be important:
I took out the power conditioner yesterday & my system has not had the usual bass/dynamics drop out:
I have pluged everything into the wall before,of course.
But this time I had the power conditioner unpluged from the wall.
Question:
Could the line conditioner have been robbing dynamics even if no components were pluged into it?
I'll know in a few days if the sound continues to stay dynamic or not.

On the 3rd page of your thread, I posted:

"-power down the whole house (including tenant)using breakers except for the outlet for audio. If there are other items on other outlets running off the same circuit unplug them. Plug just your amp directly into one wall outlet and just your CD player into the same wall outlet. Retest."

Intentionally or unintentionally I think you are just wasting everyone's time.

It sounds like when other stuff is plugged in that your amps can't get enough clean power delivered to them.

I'd guess you're getting a voltage sag and the line conditioner as well as other things in the house are contributing.

A PS Audio P5 would solve that.
