Ken and Taras of Teo Audio have been making their liquid brand cables for many years and I do believe contacting them with your budget, ends and length then they will let you know what they can build and price.
I just bought a 2M XLR cable off them. I wrote to Tares my need and Ken built me their best XLR cable and gave me the price to build it. Easy to deal with both of them. Remember they are not a huge cable company so patience is a virtue. If I can do coming,from New York, than anyone can do it 😎
4Life,
Send them an E-Mail and see what they got cooking. My 2M has no name I believe so I named it laughing gas. Makes me drunk every time I fire up my system.
