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 the Isotek Sigmas.

Wasn’t prepared for how good it is.

Alan Sircom’s review on the Nova is spot on.

Your system takes less effort to make music.

It also doesn’t change the tonality or dampen the sound.

It just lets your component sound like the best version of itself.

Thanks Milpai...

I looked into the AC-3500 and it looks very similar to the Isotek Aquarius and Sigmas. But also lacking some of the key features in those that have me looking that way. Also it looks like this is their first go at a Mains conditioner. The price looks good, but I like to stay with experience in this realm. Isotek and PS Audio have been doing this for a while...

@flip49er,You should really try out a Inakustik AC-3500P. It positively changed my system.

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.

They have a new model the Nova that is a larger Sigmas with a Synchro unit built in.

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...

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".

@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.

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?

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.

Today, if I had it to do over again, with products that have subsequently come on to the market, I'd almost certainly buy the Inakustik 3500. Though I'd be tempted to audition the Lab 12 Gordian first.
