Custom Phono interconnect build-out shops or vendors?

look on the Audio Art web site.

They hand make their cables and are actually quite nice when I've compared them to much more expensive cables.

they are my go-to cables now.  I just bought a DIN to XLR  phono cable from them recently which blows away the cable I used to have there.

I just received a custom made phono cable from Analysis Plus. They offer cable options such as varied DIN angles, RCA or XLR connectors, and length. I chose their Silver Apex series. 

Since they are new and I only have a few hours of use with them, all I can say for now, the sound seems to be even keeled across the listening frequency spectrum. The bass seems to be very taught and articulate. I am experimenting with these and possibly other cables to see if I need to actually address phono cable issues. My system is at such a high resolution playing level now, I feel as if I am chasing things and searching for something I really don’t need. I am willing to splurge and throw substantial funding here, but so far, don’t think I need to. For comparison, my go to custom phono cable is the Silver Breeze...they closed up shop a few years ago. Still going strong. 

Origin Live has multiple options that most likely include what you want.  They have then options of RCA/XLR all the proper grounding along with the DIN direction options.  I have one of their Silver Hybrid RCA/right hand DIN cables I’m getting ready to list.  Very low hours as I upgraded to a new OL arm and had the same cable made continuous in that arm.  Go to their website and look under “upgrades” for their cable options. Choice of length and connectors is in the checkout process which you can exit at any time.  

Thanks all! Very great info and generous offer from @mijostyn.
