The problem is if you use single-ended rcas on differential inputs (which a lot of amps have, you WILL get noise, but not vise versa)
That's not really true. A single ended source into a diff input will simply put a zero volt ref on one of the diff inputs and signal on the other. The diff input won't care.
Where you run into trouble is a diff source into a single ended input. You are grounding half the signal chain.
