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.
