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!

I think what your hearing is noise floor dropping at night. Try a passive conditioner, PI Audio's Uber Buss is best bang for buck out there, I think around $1100 new. There hard to find used, they sell really fast and new have 30 day return policy. 

I've always noticed that music sounds better at night.  I've wondered about the reasons... is it due to less use of the electric grid, less visual sensory input, less outside noise, or that I'm more relaxed in the evening and able to focus more on the music?  I don't know.

I'm not sure it's anything that needs to be corrected.
Its because your brains alpha waves are in a more relaxed pre sleep state not because of electrical issues.
Less sunspot activity, less traffic (cars, subways, trains, buses), less RF.
