Power Conditioner, which of these 4 and why?

Try the Add Pwer Sorcer 4X.

Consider a used Ayre L5xe. It was highly recommended to me by someone with strong technical credentials who helped me sort through all the marketing hype to find something better than a high quality power strip to plug my front end components into. Great build quality, four outlets, dead quiet backgrounds. Using it with a WyWires Platinum Series power cord but you can get away with any good quality power cord with this unit.

If strictly limited to those 4, then Audience.
If not limited, without a doubt the Inakustik AC-3500p.

M, not trying to hijack, just curious. How is the PL integrated working out with the Triton 1R speakers??? A good match? I have a PL integrated also.

I don’t know about the others. But if those you listed I have the Shunyata MPC. There is some filtering going on with them. I think there build quality is terrific. You may want to add a Shunyata Defender. But a better solution in my opinion is to get a PS Audio PowerPlant. That unit will complete regenerate your power into a clean sine wave like no Power Conditioner can do. That is how I have gone. I use my Shunyata MPC and PS8s in my two systems as extra outlets and power distributors for my PowerPlants. Wall outlets are Shunyata too. I also bought on Amazon some Green Wave dirty electricity filters. With all that I have been very pleased. But the core of the power handling is the PS Audio PowerPlant.
