I like to use shielded cables when I can, with the idea being that the shielding may reduce noise picked up from nearby wiring.
Even if the unit has a 2 prong IEC connector a shielded cable might be worthwhile.
Will An Anthem AV Receiver Benefit From An Aftermarket Power Cable
I recently simplified my home theater system by moving from
separates to an Anthem AV receiver. The Anthem is internally
grounded so the stock rubber cable has just two prongs.
So would there be a benefit to getting an aftermarket cable?
In my analog system, I use Cullen or similar priced cables,
I would be in the same price range for the receiver.
