Power line conditioners- to use or not to use? That is the question?

I'm about to buy an NAD M32 with Focal Aria 936 speakers. Dealer recommended the IsoTek EVO3 Polaris 6 outlet power strip/surge protector (with 1.5m Initium power cord). Anyone have any thoughts (good or bad) on this power strip/surge protector?

I use isolation transformers from Plitron. They sell directly to the public. The hospital grade units require their own electrical boxes, and may require a specialist electrical inspection, depending on your jurisdiction. Plitron also sells stand-alone boxes, which I have not tried.

I protect everything with Plitron units (3 of them). I found that special cords or other power accessories were less important than the Plitron.

A word of caution though - when they are doing their job, they tend to growl, so it’s better to site them away from the listening room. And pay attention to grounding. I suggest having a pro install them.

There are good ones out there. The PI Audio UberBuss is great and perhaps even better, and more neutral, the Zenwave Audio version of the SurgeX.

I no longer use them though, as my power at my new(ish) place is much better. I find these conditioning devices only necessary if you need them, if that makes sense. For example, at my previous place, I could not get along without the conditioning, and the difference was really, night and day.

I have DC on my line plus about 8% distortion. I’ve tried multiple conditioners and DC blockers. All reduced dynamics in my system except for the following:

Emotiva CMX-2 DC Blocker and Line Filter

All of my sources and preamps are down stream of this unit. Amp is plugged into the wall. Tried PS Audio Humbuster, Furman, DYI and others. Also tried a PS Audio Premier regenerator upstream from my sources and preamp. I was neutral on this unit in the end as it did reduce the distortion but did not remove the DC. Also seemed expensive and did not notice a difference in sound. 

Consider a power conditioner like any other component.
