hi, ive seen a pair of SPECTRAL AUDIO dma 360 mk2 mono amps for sale, at a fare price, but they are in Switzerland, and im in England, after checking both country's, they seem to run the same 230 volt 50hz electric system, as i have a dma 250 at the moment, it would be a fantastic upgrade, so WILL I encounter any problems running them in England, also as we have no importer in the UK ,if anything went wrong i would have to send them back to the USA for repair,ive had spectral audio for the past six years problem free,, all comments welcome thanks andy,,,
