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...

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...
They have a new model the Nova that is a larger Sigmas with a Synchro unit built in.
I've had a Sigmas Evo 3 and PSA P10 side by side. In my system, with the components I had then, the multiwave adjustments on the P10 created various levels of hum on most settings. I bought the Evo 3.
I concur with twoleftears. I owned a P20 and had nothing but hum issues. I ended up buying a Torus RM20, which I love. A friend of mine swears by the IsoTek.
@flip49er,You should really try out a Inakustik AC-3500P. It positively changed my system.
