If so, which one do you prefer?
thanks.
The one that comes with the unit is your best choice (unless it is defective). A third party power cord will NEVER make it sound better. it is against the laws of physics.
Actually, physics is the reason that the good power cords sound better. What a truly good power cord does better than the stock cord is to transfer the energy from the socket to the device more efficiently.
However, I've always seen the cord and cable thing as an incremental increase. I know that many
say that changing a power cord "dramatically" increases the sound quality, to me it's always been
a couple of percent here and there.
But if the rest of your system is sounding really good and you've taken care of room anomalies to the best of your ability, there will be some modest gains to be had. If you have a really fantastic system with a lot of dynamics and resolution, you will hear a difference. If you have a very modest system,
chances are you won't here much if any difference.
This one can be argued about forever...
