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!

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.

I don't know where you are located, but my conversations with Pat at SMcAudio in CA, revealed that their power showed significant changes as the day progresses. Late Evening and Early Morning being the time when power provided the best sound.
So, it would seem that overall usage was related to sound quality.
Here on the East Coast, I have not experience such a difference, thankfully.

Hi B
I live in Argentina, far away!
That makes it harder for me to get good prices and to try new equipment. 
Thats why I started this topic. 
Thank you all for the answers

Yea, I notice a difference in sound quality after midnight with or without a conditioner. When I first installed a good conditioner in my system and the music stopped for a split second in the middle of a sound it was so quiet I thought my amp blew, scared the hell out of me and I jumped out of my chair to shut the system down.
