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?

Sounds like something is wrong with the biwire cable. If you can bypass it give that a try! It might open up when warmed up.
How do you know that the cable is not defective?How do you know the binding posts on your amp are not defective? I would try some inexpensive speaker wire like zip cord in place of the Audioquest and see how that works. You will solve this problem it just takes one step at a time.
Did your speakers come with straps to connect the woofer and tweeter posts if you did not want to biwire? If they did just reinstall them,if not just use a small piece of wire and connect them together. Remember positive to positive and negative to negative. If that works that means something is wrong with your speaker cable or connection. Do you understand?If not get back to me and I will walk you through it.
