Loss of bass & full spectrum sound

Can anyone shed light on my audio system problem?
I have PSB Synchrony one,Musical Fidelity M6i + cd player & turntable along w/video
The sound is Full with deep bass then after an hour it reverts to a different unenjoyable presentation with no life..
This has been going on in my NYC apt for about a year
I have a great sound then it changes (white-washed).
I adjust speaker cables(AQ biwire comet)& occasionally it regains a full body sound however after about one hour it's gone.
All my components have been checked to function properly.
I suspect an electrical problem but voltage is steady 120
Any similar experiences?

Not likely. But I agree with everything you've said. IME, you really do need 8awg, all the way to the power supply itself. Change it out in your amp and you'll be blown away.

Is it possible that the speaker drivers have a defect which shows up after they have been driven for a while?

You might also try a different outlet using a 12g extension cord. You could also go as far as trying an outlet that is on a different breaker.

That's interesting
I had PSB Synchrony II & figure Synchrony would give more bass (which it does when working) but never tried different brand speakers.
I like PSB Synchrony sound and no one else has problems with them.So would probably discount a driver problem with the PSB

I tried every outlet in my apartment with the same results..
Sometimes the bass would be full & taut but would quickly go away
