Puritan vs niagara 1200


Puritan psm 136 vs Niagara 1200.

Wich one would be the better choice to clean dirty electric?

A friend of mine is thinking to buy one of them for his Hegel H390.

I myself do use this Puritan power optimizer psm 136 with my Hegel H590 (2x300watt) and an old Sony cdp-xa50es cd player. I do like this Puritan very much.
thei
I already do have the puritan psm 136.

I only was asking for my friend who has a Hegel h390 wich of both is the best choice. Prices for Niagara ir puritan are almost the same here , so price is not the problem.
thei, you might want to check if the 1200 is even instock in your country, it isn't presently readily available in the US from some websites I've looked at e.g. Upscale Audio which is located "next to them" states " Ordered with Manufacturer. Contact Us Updated ETA. ".
