Power Conditioner Advice please...

I would be grateful for advice from the forum with regard to the following:

My system sounds significantly better in the evening/night than during the day and given that I live in a busy commercial area it would seem likely that I need to clean up the power. 

Ultimately, I will buy an AC regenerator but do not currently have the budget for that. I am therefore looking at a power conditioner and which I hope to buy pre-owned for under $/£1,000.

Given my amps draw a large wattage (peak 400w into 4ohms) I am nervous about placing a conditioner between them and the mains.

The other components:

1.     Auralic Aries - has its own external linear power supply.

2.     DEQX  -  “Nine separate power-supply regulation stages  including four that provide the main analog rails deliver extremely low measured distortion....”

Where do you think I would be best to apply any power conditioning?

Any other suggestions welcomed.

Thanks very much

@inna   I had the PS Audio Premier, actually 2 of them.  My first one suffered a complete regenerator failure as I was trying to run my entire system including power amp off of it and it just couldn't handle it.  PS sent me another new Premier which worked well without the power amp connected.  I had that running off a PS Duet.

A few months ago, I took PS up on their trade-in program to get a P5.  After a few good discussions with customer support, I was assured that I could run my entire system through a P5 with no sweat.  I'm happy to report that everything I was told is correct.  With my line stage, SACD player, phono stage, two outboard power supplies (one for phono stage, other for the modded SACD player plus a heavily modified McCormack DNA-1 amp plugged into it and I am using 38% of its power delivery capability.  

Listening to Keb Mo's "Slow Down" disc right now at live volume and it is dynamic as He**.

@willemj   The happy listening at night is more likely the result, especially if you live in an urban area or near an industrial zone, of fewer devices being used on the same grid introducing all kinds of distortion into the AC.

Had a dramatic demonstration of this at a stereo shop years ago which was right next to a pizza shop.  When that pizza joint prepared to close and they shut down all the ovens and grills the sound was transformed.  Not sure I would have believed that could make such a difference had I not experienced it for myself.

Thanks to everyone for all your input, it’s great to get a range of opinion. The Dectet looks like an ideal solution so thanks hifiman for that spot on reccomendation.

Re background noise - whilst I do live close to an industrial area and town centre, my house is a way off the main road and the immediate area is very quiet, plus my listening room has double layered rockwool between brick and sound proofed plasterboard so it’s very quiet inside and means I can crank up the volume late at night without upsetting the neighbours!

PSaudio makes some nice stuff and they are easy to talk to-ask questions. I have had the Premier and traded up to the P10. The P10 works great, but i would not plug a medium size amp or large amp into it. I found they sound best direct to the wall. Sound stage suffered when amp was plugged into the P10, but still a very good unit. I now use High Fidelity MC 6 Hemisphere. Made a big difference in sound across the board better than the P10. The down size is you give up surge  and spike protection. MC 6 Hemisphere is not for amps, front end gear only.
Good luck

Thanks Pete. Appreciated. I will revisit your advice when I look at regenerators.
