I’m wondering about the advantages of keeping everything in the system fully balanced?
The Freya + is fully balanced or SE. I don't hold any advantages for balanced, unless you want to run >10mt interconnects.
Quite a few sources, poweramps, preamps have balanced inputs/outputs that are fake, in that the circuit is SE and all they do is put a balanced opamp there to give you a balanced input/output, so they actually in this case sound worse that their SE input or output.
