Power Conditioner: Isotek, Audioquest or other?

Hello,

I know a lot of you do not like or believe in power conditioners. But I want to protect my system and improve sound and video quality.

I am trying to decide between the ISOTEK evo3 Aquarious and the Audioquest Niagara 1200 for my main system. I have read good reviews about them both, asked a couple of shops and one recomended the Niagara and the other the Isotek. Both gave the same reason: "it souds better".

First system: Power amp, preamp/dac, tv, computer, computer motitor, ruter, nas. (Probably will plug the last 4 on a different power strip)

For my second system, I am thinking about the Audioquest Powerquest 3, but I can not find any reviews. So, can any one tell me about their experience with it? I am open to other sugestions also.

Second system: Power amp, preamp, network player/dac, tv, computer and network switch. (These will all be plugged in to the Powerquest for example). I also like the powerquest3 because of the on off switch. I do not use this system as much so I like to cut the power off completly.

If you need specifics on my systems, I will give no problem.
Right now I am using 2 Salicru safe7 surge protectors, they are cheapos and probably not the best in protection or for my system.


Thanks.
