Andrew Penance - Coherent PowerMaster I

I have used various different mains treatment devices from isolation transformers to capacitor/inductor filters.

When I had the Coherent Systems PowerMaster on trial it was a very large eye (ear!) opener. It rendered my previous mains treatments obsolete immediately. I'm not sure how it does it but it works very well. In my system the main attributes it gives are, a much lower noise floor, cleaner highs, better defined bass and a more prominent midrange. Along with these improvements came a much wider soundstage, this necessitated moving the speakers farther apart and along with that came a deeper stage as well. It is now much easier to hear each instrument and its ambience, vocals are cleaner and better placed. All this is without loosing any musical integration, not clinical in any way. It has none of the bad attributes of some other types of mains treatment, for instance, I found that capacitor/inductor filters can have a detrimental effect on dynamics. The Power Master has no effect like this at all, in fact I believe that due to the lower noise floor, dynamics now have way more punch and almost seem faster.

The unit itself is very small considering it has six power outlet, this makes it a doodle to hide behind your rack and helps keep things tidy. I would recommend anyone who wants to eek out more from their system gives this unit an audition, but be sure you have the cash as I doubt you will want to return it!.
