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?

Clearly, no one here has had those interference issues to warrant an expenditure worthy of paying more than the cost of the ear buds Kijanki is promoting on another thread. I bought two pair. Problem solved.
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.
