Difference in sound between day and night. Help!

Hello Guys,I'm having a pretty big difference in sound quality in my system between day and night.

During day time the system sounds very very nice, but during night time it sounds superb, amazing, incredible, I dont have enough accolades.

I have the Audio-GD R8 DAC, the Audio-GD Master 1 preamp and a Nord Acoustics Class D Power Amp (wich is a hell of an amp) and I think the most sensitive to AC Power noise/problems is the R8. I also have the Wyred4Sound USB Reclocker, but as it has a dedicated Swagman Lab Linear Power Supply, so I don't think it is the problem.

I also have the Bada 5600 Power Filter, three PS Audio Noise Harvester, DH Labs Power Cables and good connectors (Wattgate) on all the different parts of the system, but it seems to be not enough to better completely the AC Power deficiencies.

As anyone experienced the same and corrected it? How?

I prefer to keep the budget under 1.500 USD, so most of the Power Regenerators offered on the market (PS Audio, etc) can't be considered. What about the Dussun X800 Pure Power Supply Regenerator? Has anyone tried it or tried any Dussun product? There are a few pretty decent reviews of Dussun products on Internet, but not much.

I cannot install a dedicated Power Line for my system, I can only use the shared AC circuit.

Thank you!

Is it actually dark/dim in your room at night and light during the day? If so could be at least part of it is you are less distracted and more focused on listening at night.

Also could be you are less stressed/more relaxed when listening at night so you respond more positively.

Don’t assume none of it has to do with you the listener.

Was that audio engineer one of the SOBs who have been compressing the life out of our CDs for the past twenty years? Have they been teaching neuroscience in audio engineering schools? I did not know that.

Don't knock it till you try it there johnk, you have no idea what your talking about. First Running Springs Audio (passive)conditioner I bought I told no one in the family. My wife came in the room first day( not at night) and asked what did you buy " that sounds really good" she could careless about 2 channel audio. Even my kids noticed without telling them, they listen to music off there phone. Explain that one johnk

Hi Paul
For me the differences are too obvious to believe they are generated in my mind.
I feel them all the time and in different hours in the night and at different volume levels and many times I felt them with out any previous expectactions whatsoever. It was like getting a nice unexpected surprise. 
There is some technical explanation and there must be a technical solución, at least a partial one.
