I will start by saying that I rarely use the stock pc’s on any of my gear.
I have a c900u/m900u combo, and several nice pc’s to try from nordost, audioquest, and others. I found the supplied pc’s were best, just like with Shindo gear. Tough to say what was different exactly, they just sounded off. I even asked the importer about this and they also said the included cords are excellent. He said some liked a aq hurricane on them, which I had tried also.
Bear in mind that these things are voiced with that cord. Often a change is perceived as an improvement, when it may not be long term.
