    Basically, yes . Though I have bought a balanced transformer (from Airlink).

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    I read the original opening post last night: It seemed fine to me. Apart from transformer size, are all these balance mains devices much of a muchness? I'm guessing there isn't a whole host of balanced transformer makers.

    Apparently it's better to have too high a rated transformer. The two UK hi-fi manufactures who do these do make very similar designs, both 1000VA which is considerably smaller than the one I have ordered. They are also considerably more expensive than the Airlink ones (who likely make the actual transformer in the 'hi-fi ' versions).

    Have one m'self, the 2KVA one from Airlink.
    Be interested to know your thoughts Mark, big improvement here, but my mains quality wasn't the best.

    Put a long post on installing mine here on AOS way back when, and for those reading theres 'plug n play' options as well as more hardcore hard wired ones.
    If you dont know your leccy then (Blue Peter style) get a grownup to help plumbing the hardwire option in

    A mate had the Airlink box you just plug in, and that made a worthwhile improvement in his system.

    Safety aspects of these have been discussed to death, short version if you have double pole RCBO protection on both primary and secondary windings you'll be fine. Not worth doing it otherwise.
    The tripswitches in your consumer unit will probably trip first should anything happen anyway, but safety first.
    Wouldn't reccommend a hardwired unit without double protection, even despite the CU tripping.
    Dont dick around with electricity folks, not worth it for hifi.

    Very worthwhile sound improvement, as used in many recording studios around the world.
    Just know what your doing with them.

    @Mark
    The higher rated ones are said to have lower impedance, the larger rated ones are big buggers though due to larger transformer.

    The first rule of balanced transformers is that you don't talk about balanced transformers.
