interesting ralph
iirc correctly back 20-25 years ago ARC made some small boxes called Balanced Line Drive (1 2 and 3) or something like that .... could just be for this purpose.
of course there must be active components inside to produce a ’mirror’ image signal to get the full balanced voltage swing from the middle ground neutral level... op amps or transistors or transformers... ralph can this be done just with passive components? there must be a small sonic penalty to adding this in the chain... prob best to just buy a balanced pre
