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?

Hi,

My response does not answer your question but I felt tempted to write.
 
I was given seriously expensive power conditioners and cables with filters (can't remember the brands) as home demo items long time ago. To me they did not make any difference at all.

May I ask to those who say otherwise, do people around you also hear a difference? An audiophile buddy etc..

Before spending money on a power conditioner I would run a separate spur from the junction box and try passive EMI/RMI suppression. I have great experience with Acoustic Revive powercables and RTP multi-connectors
To those who say PLCs don’t work, I say, you haven’t heard really good ones. Many that I have owned obscured the music; PS Audio Power Plant, Furman; my BPT was pretty good though

I have a 20amp dedicated line to my system outlet, but still benefit from my CorePower 1800, which I bought to handle all my equipment; digital, preamp/dac, power amps. At the moment I am no longer using a preamp/dac, and could easily get along with their new 600 and possibly their Deep Core.

I did find that my EVS1200 class D dual mono amp, based on IcePower1200AS modules sounds much better direct though. But it doesn’t have a super-duper power supply, as has been suggested

CorePower from Underwood HiFi is incredible and reasonably priced.

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.

All the best,
Nonoise
