Larry, whatever you do, FOR HEAVENS SAKE DON'T REPLACE THE POWER CORD!!! You'll accomplish nothing of substantial benefit, and only end up voiding the warranty and possibly damaging yourself or the unit.
First of all, safety: I don't know what kind of capacitors the 1050 power unit has (neither do you, I venture), but if you're not careful and short out a power capacitor, it could blow! Those power capacitors can carry a lot of energy.
Second, I seriously doubt you'll see any difference -- soundhound had a good point regarding cause/effect. Power supply signals are pretty nasty due to turn-on transients (i.e., voltage spikes) created by other appliances (the fridge, the dishwasher, the heat pump, etc.)
Engineers recognize that power supplies are not "clean", and that's why they design in power filters to clean out the signal before it's sent to the audio circuitry (since the 1050 is 100% digital w/ no tubes, there's less of an effect). Power units also have voltage regulators to make sure the DC level voltages are accurate. Power supply line replacement isn't gonna make one hill of beans difference compared to what the filters and voltage regulators are designed to do.
My guess is that if you're hearing a "hum" on his tube amp or think a given cable sounds better, you're probably hearing your friend's wife vacuuming.
If you REALLY want to make sure you have a clean voltage signal, get an AC line conditioner that FILTER the line (not one of those cheap AC strips).
See this Stereophile Article about line conditioners, and try this before messing up your 1050.

P.S. If you REALLY want to shorten the power cable length, then I'd suggest cutting the plug off and putting on a new plug and the desired length.
