Equi=core 1200 OR Equi=tech 1R OR Isotek EVO3 Aquarius

I don't know if this may help, and we are an Isotek dealer so we are a bit biased. With that being said: only the Isotek has a number of features that can make a very large difference in a system.

All three units will block noise and create a more stable environment for the components, the difference is that Isotek isolates all of the outlets to eliminate cross contamination of digital circuits into analog ones.

One of the biggest nasties in audio is the digital clocks and circuits radiating noise into the analog components and addding a layer of grunge and Isotek is one of the very few companies that design their products to filter each outlet from another. 

Isotek is also very effective in emi and rfi suppression. We have been selling Isotek for years and when ever we demoed one of their units particularly their higher end ones, the change in clarity and sound staging was very noticable.

We sell Audience, Isotek, Running Springs, and the Isotek's are great.

I’ve never had the pleasure of using or hearing the Isotek EVO3 Aquarius, however, I found this interesting video: https://www.youtube.com/watch?v=i12vyTf7vyg

I do own an Equi=Core 1800 and an Equi=tech Q2. I don’t know if it makes any difference but watch the video and the ease that the speaker has when lifting and turning the Aquarius due to its less weight. I guarantee you that can’t be done with the Equi=core 1200 OR Equi=tech 1R because of their massive weight. I don’t know if that makes a difference but I wanted to go on record as pointing that out. Perhaps the three you asked about have a trial demo period depending on where you purchase them from?

Let us know what you end up with.
Best regargs...

I have to agree with @lak the video was pretty amusing just how light that unit is.

There are some really good reviews written about the Isotek EVO3 Aquarius. I'm not aware of the electronics inside of the unit, most likely another way to clean power that weighs a lot less than what I think of traditionally. Perhapes something along the line of my Shunyata Research Denali D2000/T.
