Yes i have! Using the "Original" for about one year now, i was attracted by the generous upgrade routine of Mr. Motek and got me 2 "Signatures". Placing them before 2 power distributors, in order to get the effect spreaded across the rest of cabling, i heard an immediate improvement in background silence and PRAT, fresh out of the bag. I`m not a big fan of describing soundcharacter of anything music with my insufficient vocabulary, but the chance, that you`re not satisfied, if you like the original is small, especially when taking into consideration, that you can get your money back (minus shipping) if they are not to your taste! My advice: If you really want to know for sure, try them out, it`s worth while, at risk are a few dollars for shipping them back-which i doubt you will!
