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?

The back of PSB speakers are biwire & I use AQ Comet

Proper connections are top half treble(red/black)
bottom half bass (red/black)
I was doing top half treble+bass(red&black)
Bottm half treble+bass(red&black)

2high pass
2low pass
I was connecting high/low + high/low

Which AQ speaker cables are you using? IIUC, they would have to be a thinner gauge for the treble than they have for the bass before a miss wire would mess up the bass.

If the treble wire was thin enough it would conceivably get worse as the cable got hot.

From the AQ website:
Comet is an exceptional Single-Biwire cable. When the halves are separated at the speaker end, the double quad-helix design turns Comet into a true double-biwire set thanks to the magnetic autonomy of each quad-helix. On its own, one quad would be a little light-weight in performance as it is biased towards treble finesse. The other quad is more forcefully biased toward the bass. Together they form a completely optimized full range design, but when separated the Comet becomes a maximum performance double-biwire in a single cable.
Whatever that means.
