If your PM11S3 has the ground floating, a three prong PC will still be fine. Doubt you will find an audiophile two prong cable. I believe some of the older and maybe current PS Audio PC's, the ground pin does unscrew off the plug. Again, a three prong cable will be just fine. I think I'd look at an unshielded cable since you're not using the ground. There's probably many unshielded cables out there but I know Kimber and WyWires have no shield tied to the ground. On the back of your Marantz does the IEC jack have two or three prongs?
2 prong power cable
Never paid much attention until recently but my Marantz PM11S3 has a 2 prong power cable. Anyone know of upgraded power cables with only 2 prongs. I'd like to replace the stock cable for one that will help with imaging and a nudge toward neutrality since the Marantz tends a teeny bit toward warmth. Thanks.
