Is it complex to disconnect or remove the ground pin on a power cable and be able to re-connect it if you decide to sell the cord later? Any soldering required? My Wadia 302 does better without ground and there are not many options out there with removable ground pins.
I'm sure you already know this, but the presence of a ground connection indicates no double-insulation, so removing the ground does expose you to the small but real risk of electric shock if the casing ever became live.
Cheating out the ground may get rid of the hum but the problem isn't that you have a grounded chassis. The way to address the problem is to find the cause and address the cause. As Carl109 pointed out that the 'fix' of cheating out the ground has its drawbacks.
I have read somewhere that my Wadia 302 is known for this and is actually suppled with a 2 pronged plug (without ground pin). I can't say for sure since I bought my unit on the 2nd hand market, the cord supplied wasn't the original...perhaps I'll send an email to Wadia. I have had 4 or 5 other CD players on the is receptacle and no problems til now.
