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?

I have been introduced to a new type of power conditioner, the first of it’s type I saw was from Germany. However the second one, introduced to me by an Agon member is the one I purchased, is from England.

The one I purchased has two transformers in parallel to support the current load, and it has protection from power spikes, nothing too different here.

Then it has capacitors in the circuit that effectively remove DC from the AC.
Individual for each outlet.
Then there is in the shunt to ground off the AC sine wave. This filter has individual inductors on each outlet that are a high pass filter then in parallel with both the active and another for the neutral short energy back to ground.
What does that mean? Frequencies interpolated in the AC sine wave that are riding on the alternating current are shorted to the ground wire back to the box. The path of least resistance isn’t into your bridge rectifier, stiffening caps, linear regulator, it’s back to ground.

There’s no current limiting, the current carrying conductors are still only added to in parallel, and this draws away the nasty hash from the alternating current.
Others have also commented on the incredible difference it has made.
Being USD$2400 it was cheaper than the German made device, with individual filtering for each output device, so no chance of noisy devices affecting another.

Thank you Agon, for the free advice and the best conditioner I have heard or used.

I have a Datasat RA-2400 that’s a two by 400watts @ 8Ohm amplifier, my TV (I use it as a monitor), HDPlex 200W linear power supply (for my fanless PC server), DAC and the MCP thing for my Synergistic Research Master Coupler X2 20A power cord feeding it - all running through the device. It performs perfectly, and the system is cleaner with no loss of power that I can hear.
That sounds really nice @rixthetrick do you care to share what devices it were? I believe Isotek or Isol-8 does something like that, no?
So the German one is the Inakustik AC-3500P (which I was almost going to buy, I just had a little more money to squirrel away for it)
Then I was in contact with an Agon member, who I asked what he has, he shared and as I was already interested in the Inakustic saw the value in the Puritan.

As for the Niagara products, I have only ever read or been told good things about them also. For me the price / performance was a best fit for my budget was the Puritan.
Audioquest Niagara 1200 is the best! Don't have to mortgage house to get one and it works! Very black back ground and the music leaps from my speakers. I hear what I hear, your results may differ....
I added a Niagara 1200 last year and experienced an immediate improvement in SQ.  Blacker background to music, individual instruments were more distinct, the slightest nuances of music became much more defined.  I'm now changing my system layout by adding a Symposium Acoustics Foundation Rack Ultra.  I'll leave the Marantz theater processor, multi-channel amp, and BD player in my present cabinet/rack and use the Niagara 1200 for those components.  I'm adding a Niagara 3000 for my main audio components going into the Foundation Rack Ultra.  For that setup all power cables are Audioquest Tornado (High-Current and Source).  
The bottom line is that I was so impressed with the outcome of the Niagara 1200 that I am taking everything to a higher level by reconfiguring the system and adding the Niagara 3000, connected to a dedicated 20 amp line, specifically for my main rig.  The Niagara products work exceptionally well.  I stand by them and can't recommend them enough.
