There are so many good cable makers these days who sell direct and offer generous trial periods, why not just try one of those? You can get a Cullen Cable Red Copper PC for $81, which isn’t much more than your DIY target? Then again, good cable by the foot from Furutech, DH Labs, etc. along with Wattgate, etc., connectors are readily available that you might have fun cobbling together. Either way, I’d be surprised if you don’t hear a meaningful benefit from upgrading over stock cables. Best of luck.
DIY PCs
I am thinking about upgrading my system power cables. First off, I should confess that I am an objectivist and a cable skeptic. That said, I see nothing wrong with a little bling in the cable department. I don't think any of the present PCs are stock, they are lab grade molded connector types suitable for lab test equipment. I will need four PCs: Pass INT-150, Oppo UDP-205, and 2 x ML Montis. I will most likely go DIY and would like to spend around $50 each. Any suggestions? Thanks in advance for your replies.
