I currently have 2 of the Synergistic Research's Absolute Reference power cords in my system. They have been in my system for the past year with incredible results. For the first time I understood what a power cord can really do for your component. I belive that to a degree power cords do have their own sound but what the good ones do is they let your equipment sound the way they should. I have older Rowland gear ( amp, pre-amp ) and I have tried with good results power cords made by Purist Audio ( their Dominus ), Shunyata's Anaconda and Harmonic Tech's top of the line cord but the Synergistic Research's Absolute Reference power cords were the first ones to make my equipment sing. I truly heard what my equipment was capable of sounding like after owning the Rowland stuff for years !!! It has balance, the bass was dead on, the highs weren't thin and tin(ey)and the mid's are to die for. The MPC actually does work as you can test it for yourself by turning it on or off...it ''cleans'' things up just a little more. One other thing, this is a big heavy cord....and if you go with Synergistic, your being backed by an established and solid company that is going to be around for awhile. Mitchb, why don't you contact me personally as I may have something for you.....
