"Musical" Power Cord ?? From my experience a power cord removes unwanted things in the power path, that are getting in the way of the music.
Therefore, the equipment is musical. The power cord just removes whatever was making it less musical. If the audio system is not musical to start with, a power cord is not going to save it.
Thus my earlier comment about the law of diminishing returns. A good $200 to $300 power cord is going to get you most of the way there. After that, you are spending a lot more for not as much return. But if you feel your system is worth it, then go ahead and spend more.
