Better XLR/RCA adapters


I know, I know, that's not audiophile way, but I might have to temporarily use them. I heard that Purist Audio is considered the best by some but they are $500 pair, and I don't want to spend $1k on adapters.
So what should I get? Cardas ? Specifically, I would use XLR cables and the current equipment is all RCA.

Why would you want to the single ended connections will sound better than the balanced ones on most if not all gear anyway.
I might be getting Otari or Studer reel to reel deck in the foreseeable future, they have balanced connectors and for a good reason. That I would not want to use with adapters. So if I see a balanced cable that I would want to use with the deck in the future for sale and the price is right, I might buy it now. In the meantime I would be using these high end cables with adapters in the current system.
What cables am I thinking about ? Well, probably either older Purist Dominus fluid or Wywires Diamond. The former is almost impossible to find, no one sells it.
