Either build your own, buy used or spend a little more. Your gear is nice enough to justify better that’s for sure but understand not wanting to go crazy. If you don’t know how to use a soldering iron then you really need to expand your budget a little or just keep what you have. If you build your own spend a little on the ends or you’re wasting your time, then look at Canare, Belden or Mogami bulk mic cable.

The Canare comes in multiple colors if you want something more fun than black. I have the purple on my drum kit and love the color. The Canare is a very nice cable; not the most revealing but it does nothing wrong either. You won’t feel you’re missing anything but the top end is a little rolled off. No cable in this price point is going to be extremely revealing. The pro studio mic cables are very good but just because they are widely used in studios don’t buy into there’s nothing better than what’s in the studio because that’s not true. Studios use this stuff because it’s indeed very good, flexible and durable, shielded but it’s cheap and gets the job done. Really easy to build your own and if you have questions on the construction there’s plenty here to walk you through it.
