Are you sure that additional cost would be fairly low. It most likely
means an output and input transformer pair at a minimum and that's a
good 70 quid a channel on its own.

Unless you were thinking unbalanced inserts?


Most inserts are unbalanced these days. OTOH you can make a balanced
insert using an LME49720 op-amp for a few dollars that will be as audibly
transparent as is possible.
