Hello! Is me again! I posted Gutwire G Clef power cord is good. But if we use it in the high current power amp (mine is Krell FPB300), the bass is a little bit less. Anyway, I tried Power Clef for it, amazing!!! Much more better than my Aural Symphonics CubeII and my friend's NBS statement. You know NBS is about CAN$2500.
