RCA, Balanced, Krell CAST, Status Quo to Nirvana?

RCA connections, almost everyone uses them. Recording studios don't, it's all balanced for them; long lines, great noise isolation, the cables null out the "SOUND" of single ended cables. The music we listen to is recorded via balanced cables.
Both topographies convert from voltage to current and back again, over and over. Krell CAST maintains the signal in the current domain. I've never heard a CAST connected system. How does the theory sound to you.

No, balanced cables null out common mode noise picked up by the cables, they still have a sonic signature just like single ended cables.

I assume you mean topologies but I don't think that conversion over and over thing is correct. Could you please explain?

Most amps use stages that are designed to act like voltage sources. They produce an output voltage proportional to the input signal and try to deliver whatever current the next stage is trying to draw. This isn't really a conversion from voltage to current and back.

Current sources like the CAST produce an output current proportional to the input signal and try to develop whatever voltage it takes to push the correct current into the next stages.

I think the CAST system is a viable solution but you are locked into Krell gear since nobody else uses it.
