Hi guy's, i just purchased a purepower 1050i ac mains regenerator with battery back-up & i am absolutely blown away with it, i had it on home trial & to be honest it was something i had been mulling over for a while but was quite sceptical what the real world outcome would be, after installing it into my system the wife and myself were speachless to the drmatic effect it has to a home that may suffer from unclean & unstable mains, the dynamic range, bass, imaging & vocal projections are not just a little better if you listen close....it is so vivid to the point that we reverted back & the difference was stark, it also has quite the same effect on bluray images which is an added bonus & all your expensive equipment has the added protection as it is completely isolated from the mains & during a power cut it will keep going for a while allowing you to power down properly, has anyone else on the forum ever tried or even own any of these products as i would be interested to hear if the outcome was similar to my own, thanks for reading, Benny.
