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!

plga-

What you are hearing is perfectly normal, and there is not a thing you can do about it. For the simple fact that anything you do to make it better in the daytime will also make it even better at night. There really is no way around it.

If you are really trying to recreate your night time experience in the day time, the closest you can get is to flip off all the breakers. Don't merely unplug appliances. That helps but leaves all the wire in the walls still gathering up RFI like the great big antennae that they are and feeding it all right into your system. Flipping breakers physically disconnects a lot of that, with the resulting lower noise floor closely resembling what naturally happens late at night.

Or you could get the Synergistic Research FEQ. And only run it in the daytime. Never at night. Otherwise.... see 2nd sentence above.

Congratulations btw on noticing. Lotta guys never do figure this one out. Plenty more won't believe it even when you tell them. Audiophiles! Ha! Since you do notice however one thing you better not ever try, waiting up till 2am, flipping off the breakers, running a demagnetizer through all your cables, spraying (ordinary laundry) anti-static spray, demagnetizing your record, and then listening. 

You think you got problems now? Just don't do it.

So power quality matters, but when I read your title, I wondered if you had a Class D amp! :)

Class D amps often take 72-100 hours to sound their best. If you are turning them off overnight, there is your problem.
Best,

PS - If it isn't your amps warming up, I highly recommend the Furman units with LiFT and SMP. Here's the "low end" version:

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.
