What about the "right speakers"? In reality don’t you need the right marriage of electronics AND speakers to realize those audio qualities??? Electronics alone ain’t gonna get it if the speakers are crap or just not a good match for the electronics. And the reverse is true as well. How can there be any discussion of power cords or power cord components without knowing about the rest of the system (including sources and cabling!) Finally, as with most cable discussions, won’t this ultimately come down to YMMV and only in-home-audition can say what works with your gear? (Barring the unlikely prospect of someone having the exact same set up and room, of course.)
