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!

As others have commented, it may be alcohol consumption that, among other things, makes music sound so much better.  Want a real boost in perceptive audio performance?  Smoke some good weed just prior.  you will quickly pick out nuances in your favorite tracks that you've never heretofore noticed.  Promise.  Oh....do not drive while doing this or after.

I have always noticed this, and have always attributed it to the lower ambient noise both external and internal, perceptible in the listening space at night.
I believe that I become acclimated to ambient noise to the point where I am not always consciously aware of it, but I can still notice the difference in my perception of the music when the ambient noise floor is lowered.

I’ve never tried to evaluate my system on a day V night survey, but I had a problem with a tripping circuit breaker. Ran a dedicated 20 amp circuit just for the preamp & power amp, only expecting the breaker to stop tripping. The soundstage depth, width, height, imaging, and bass slam was not anything I had heard previously. If you can’t run a dedicated circuit, perhaps you could try removing anything that isn’t audio related and plug them elsewhere.

Would you say the difference is day and night?

What you say jibes very well with my unusual experience. It was on Christmas Eve when we had deep snow and 0 temps. My system sounded so good that I stayed up all night listening.

Without a doubt it's "The power grid"; meaning the broader power grid had almost no traffic.

I have moved a number of times, and no matter where, there is a day and night correlation if you listen carefully enough, and what makes it even more significant is that it's better after midnight, but that difference is so close that some attribute it to a psychological difference.
