Power Conditioners


Not sure if I placed it in the correct topic but here goes. I was just wondering how power conditioners work, as I want to buy one. There are conditioners with only filtered inputs and conditioners with some filtered inputs and some unfiltered. I believe the unfiltered ones are for analogue devices. But why should these go into the unfiltered part? If I buy a power conditioner for example with only filtered inputs, will I not be able to put my class A amp in? Or will it have a negative effect?

To anyone who doubts the efficacy of a good power conditioner because they haven't heard a difference, I'd like to know if your gear has lights, meters or displays that can be turned off. 

If so, try turning them off to see if you can hear a difference. If you can't, then it's you and not the conditioner, or, your system is simply not resolving enough.

I say this because when I first got my Marantz Reference gear (integrated and SACD player), I tired it with the display on or off and couldn't hear a difference. That was before I got my Niagara 1200 and the Isoacoustic Oreas. On a lark, I tried it again and the difference was big enough to make me reconsider a lot of things. 

There's now so much more air, separation, detail and nuances laid bare that those dirty LED displays were injecting noise back into the gear and superimposing itself on the music, blurring things more than just a little.
The line noise was so dirty that it helped cover the negative contributions of the LEDs. 

Before my getting the Niagara 1200, I thought LEDs and displays had no real effect at all.

Don't mind mc. He's a legend in his own mind, ever ready to drop an insult, brag about (you guessed it!) himself, and denigrate others at the drop of a hat, like he just did.

again. Snake oil. 99% of electronics will already rectify/filter 99% of the noise out of the PSU dc lines reducing down to a miniscule ripple. You will not hear any difference. 

İf you are hearing a difference, you must live somewhere where your power company should be taken to court for not being able to provide even the basic service
100% pure, unadulterated ego speaking here.

If I built it, no one can improve upon it. Instead, look at it this way: something's come along that can truly allow my gear to shine the way it's supposed to.

It's obvious you didn't read the link I provided.

Bull pucky. It's not snake oil, no matter how often someone gets up on their soapbox and yells at passerbys.

 I've measured the AC over the course of many days, all day long and it never varied more than +/-2 volts.

No lightning strikes here either.  All gear is built to a price point and based on tech from many decades ago. I thought everything was hunky dory until I got my Niagara 1200. It was no contest concerning the difference.

To infer that all equipment out there is improperly designed and built i(if you end up hearing a difference) s silly and misleading.

Here, read this from John Atkinson of Stereophile (the king of measurements and always quoted by the naysayers as some kind of justification to rely on measurements only)

The article is about op-amp chips but goes into some depth on the lack of proper measurements and the equipment needed for them. Small things have a very large effect.

Until half a year ago, I always went directly into the wall. Whether it was BrickWall, TrippLite or Blue Circle, they all limited dynamic range and soundstage size, resulting in everything else following suit.

With the AudioQuest Niagara 1200, none of that happens. The noise floor goes waaay down allowing everything else to shine. Absolutely no loss of anything across the frequency range. Dynamic range is superb as well. One of the best investments I ever made.
