Hello:
Have you thought of making your own cables?
Get the raw cable from Beldin, mogami, or other company that make the raw cables. Then get the connectors from company that make connectors like Furutech. Get your solder and soldering iron and you are on your way.
Most companies that make interconnects don't make the cables or connectors, they just assemble them and make them look pretty.
I have purchased very expensive cables for my audio system and upgraded several times. But it came to a point where I performed listening test with my executive cables and cables I made up myself using Blue Jeans cables, mogami and Belding cables and I when I compared my DIY cables with my expensive cables I couldn't tell any difference. The reason I went DIY is that after purchasing the expensive cables I immediately heard a difference in the system, but after a few weeks that excitement wore off and I began to wonder why. No answer than to say because it's expensive it must sound better. Nonsense.
Try some DIY cables and judge for yourself, only you can decide what sounds best to you. There is no magic bullet in this hobby.
