Isotek Sigmas or PS Audio P15


Anyone have thoughts about these two gems?

Better yet, has anyone compared the two? Would really like to know how they stack up against each other...

Need something for my crappy power, and I have honed it down to these two.

Would like to know what you guys think...

I have had both and preferred the Isotek Sigmas. I thought the PSA  added a layer of distortion. The PSA does work great for a TV.
I am also thinking about buying the Isotek Titan because I am really wanting this for my PASS 30.8. I have an AQ Niagara 1000 that is pretty good on the regular plugs, 000 with a line noise analyzer, but the High Current on it sucks. Reads in the 700's on that analyzer. I have seen 000 on the High current of a Isotek Aquarius. I am sure the Titan would be better.

Any thoughts on the Titan guys?
@flip49er  I too have a Pass 30.8.  I use the Isotek EVO3 Syncro Uni Sine Wave Rebalancing Unit in front of my AQ Niagara 1200 and really like the results through the high current plugs.  I have only compared this to going straight into the wall receptacle and it makes a huge difference.  From my limited experience I am fan of Isotek products.  I'd be curious of your results depending on the product you choose.
Open your audition list  and include the Audioquest Niagara 7000. I have owned the PS Audio units and many other "conditioners". The Niagara is in another league. You can feel the "boogie factor".

That sounds like a great idea, but I am ready to push it to the next step. Been saving for this "foundation" for a while. 

If I get the Titan or the Sigmas, I would get the Syncro PC to go with it in the future. My PASS has a very slight hum...Very slight, but it is there.

The Titan and Sigmas are very close in price and I'm sure both would do what I need to start off.

The community on this forum is VERY informed, and always like to hear what they think when I am wanting to spend some money...
