Power Conditioners

I’ll second the Audioquest Niagara 1200, it was worth every penny. I use the Audioquest thunder high current power chord for my amp, and the rest are all Audioquest X3’s. The Niagara is plugged into the wall socket via a Audioquest Z3 power cable. This is all on a dedicated 20 Amp circuit using 12 gauge romex. What I cannot fit into the Niagara goes into a Furman pst-8, another great power conditioner/strip. The Furman is plugged into the same 20 amp dedicated receptacle, the Audioquest NRG. I think my system sounds great. Lots of dirty power here and numerous thunderstorms. All this was very expensive to me, but worth it as I only have to do it once. I’d probably be dead before any of it wears out significantly, if at all.

One more question about these power filters/conditioners (is there a difference at all??). 
They have these markings to put everything in phase. That's wonderful, but how can I put a wall wart in phase? Is there any method to know which of the connectors is live and which is neutral?

First thing, do you have any issues with your system? I forgot to ask.

Second get a multi meter, if you don't have one, STOP.. Don't get hurt, get some help.
DO NOT work on hot circuits, no multi-meter, NO WORK!!! i
If you do know what your doing, are comfortable, and NOT COLOR blind, (I ran into that to :-) )

White = neutral
Black = hot
Green = ground
Bare = ground
red = aux/hot/jumper/assignable

Phase? reverse the black and the white, when there is no ground?
or is it direction on the cable?

These are questions for you, don’t mix them up, yes direction matters.
Cables, normally work better in one position or direction, unless they are already set up that way. Male, female as an example.

OR Don’t use a wall wart, and use a good SURGE suppressor and a maintainer. It’s not a SQ issue FIRST for me, It’s a safety first, protection second. BUT SQ won’t suffer, with good Equipment and protection.
Let it settle for a while, rout your cables correctly...Get them off the floor.
It’s your equipment, I protect my expensive equipment, plane and simple.

Thanks for your post @oldhvymec but I have a hard time understanding what you mean to say :-D

What I try to accomplish with my system is better SQ, less noise. I’ve had a filter before and it helped a lot. Now I want to buy a new one and I want to set it up as correctly as I can. So everything in the correct group and all devices in phase. With the regular power cables it’s easy to put it in phase but the wallwarts and power cables without grounding it’s hard.

You do NOT need them, unless you live somewhere with a lot of lightning strikes. Other than that, there is no need. The filtering in the PSU of your devices are more than adequate. The rest is mostly snake oil or the improvement is so insignificant, it is not worth the expense.

If you have hum or noise issues, they are typically due to other reasons.  Those typically occur when you connect 3 pronged (with an earth connection) plugs to DIFFERENT outlets.  The miniscule potential difference which exists between the different earth points are what causes hum issues (earth loop).  Make sure that ALL your 3 pronged plugs connect to the SAME outlet, making a star connection.
