@jfrmusic "Accuphase strongly recommends that you use only the stock cord and so far that has been the best"

why not to rely on on Accuphase advice and to start enjoy music?

Because we’re enthusiasts here always looking for ways to improve sound and our listening experience. This hobby is about music, the gear that reproduces it, and the quality of the reproduction. If it’s music only enjoyment, any $50 half decent Bluetooth speaker would suffice  

Accuphase Engineers choose carefully IEC receptacle for amps and cable to active highest performance and not to damage amp using unknown plugs, which typically could rip off contact’s plating/make scratches etc.

Accuphase like all manufacturing include a decent certified power cable that gets you started. There’s nothing wrong with trying a good aftermarket power cord to scratch the upgrade itch, satisfy curiosity and may be improve presentation. No plugs will scratch the IEC connectors. I’ve not seen one yet with any of the power cords I ever used. 

@audiophile1 "No plugs will scratch the IEC connectors"

as an experienced analog design engineer I can say this is not correct! typically product from established hi-end company chooses IEC receptacle and plug (or assembled cable) from one company (Kawasaki, Amphenol, etc), which ensures reliability and interconnect performance for decades, because interconnect is checked many times and contacts are inspected for scratches, plating surface damages etc. 

wondering, if you ever looked IEC plug/rec. under microscope after experiments? Please keep in mind, after you scratch contact surface, contact resistance could dramatically  increase, and then plugging “new fancy” cord will give you relief for few days.. then you need to try to “improve” sound again, by buying new PC :-)

- maybe in micro circuits, chips and tiny components, but in IEC plugs & receptacles, I don't buy it ... 

Cheap chinese rubber power cords with molded plugs don’t scratch IEC connectors. But the good wattgate and furutech gold plated plugs do. And who inspects IEC connectors in their components under  the microscope?
