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?

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

What gauge do I currently have?
My cables are Audioquest Comet biwire

I've noticed it's eaiser to get one speaker working with full spectrum sound after pulling out speaker cables.
When I try for both speakers after "I found the bsss working properly" it's more difficult to get both speakers to be working together.
The slightet break in the circut like changing Records or different sources eaisly knocks out the lower full bass.
Even with the one speaker after 'bout an hour the sound changes and the taut bass is gone.
Left with music with no emotion
I am thinking of buying PS Audio P-3 power station
Anyone have helpful insight if this would help?

My guess is the you have a intermittent AC connection acting as a diode either In your AC box, a sub panel,circuit breaker or where your service starts in the basement.
Call an electrician, and make sure he tightens up on all of the possible connections.
We have seen this in the AC box as it arcs in and out spoiling the systems performance.
No power cons will correct for this.

Have you thought about the interconnects?There was another thread about a loose connection internally that was discovered by carefully twisting the connector as music played.It's worth a try.
More to discover
