They made me custom Phono cable, my length, my special din connector, very cooperative, high quality.
I am into Locking RCA connectors these days. I bet they would make you interconnects with locking connectors if asked.
I make my own speaker cables using Cat8 and WBT spades. Their speaker cables costs are very reasonable, remember, the prices are for pairs of cables.
btw, you can get different colors, easy to identify this from that
