Thanks for all the input. My preference is to replace the cord with a new 2-wire higher quality replacement, hardwired. The cord entry point is pretty tightly close to one of the speaker terminals so adding/converting to an IEC inlet will necessitate chopping part of the chassis which I prefer to avoid. Need to take a peek inside to see if its something I could do myself or get some professional help.
P.S. Full disclosure, better power cords did make a difference in sound quality in my other components, albeit very subtle.
