I bought a pair of DakiOm MR273(s)and placed them between my Rowland Preamp and Amps. It produced a dreadful low-end buzz that I thought might blow up the system. Tried it with Rotel gear and it dimished system performance significantly. I tried to return them but the owner/manufacturer refused and was incredibly rude and dogmatic. As far as I'm concerned if I would have paid even a single penny, it would have been too much for such a pathetic product.
