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?

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.

What gauge do I currently have?
My cables are Audioquest Comet biwire
Audioquest does not publish specs regarding their cables gauge or electrical behavior, for some reason. I'm guessing here, but I doubt they offer large gauge speaker cable for their low-end or mid-range lines. Like many cable companies, they save the large gauge wires for the big boy$$$$.

The suggested large gauge cables are an affordable way to bring low resistance signal transfer from your integrated amp to your speakers. Given the same cable design, a larger wire gauge should yield lower resistance values.

Don't waste your money on the Highwire Powerwraps featuring voodoo science.

@ fishing716,I believe I would start with your power at hand!,high -end recepticals for each componet,a dedicated 10 gauge electrical line for each componet,with a dedicated ground for each componet with a 20 amp breaker for each componet, this is what I use,problems?,I have none!,the sound will improve dramatically as well!,this will take a few hundred dollars to do,the pay-off sounds in the thousands!Happy listening!

I'm sorry but don't understand all these details such as 10 gauge electrical line(what is that?)
Also 20 amp breaker(what is that?)
I apologise if I'm not knowledgable of electrical terms as you assume.
I'm just a music listener
