If so, what would be the downside, compared to just having an unbalanced setup to begin with?
Is this essentially what the re-zero trs adapter does?
Sorry to hijack on your thread but if you have SE amp with balanced headphones, does it matter if your source is balanced or not? And what do you mean by a balanced source? Many thanks.
Here's another question.
If you have a balanced source, and a balanced amp...but only an rca interconnect cable...would rca to xlr adapters actually work and send a balanced signal to the balanced amp from the balanced source?
A proper balanced connection requires positive, negative, and ground lines for each channel.
If you're willing to spend what it takes to have all-balanced hardware, why wouldn't you be using the appropriate cables?
Or just positive negative for each channel and a common ground.
Just make one. You just run the negative signal wire on the adapter to the ground of the 1/4 plug, so two will go there and then you have the R and L channel. Almost all my phones are balanced and I have adapters for 1/8, 1/4 and other balanced outputs. Very versatile.
