If the active line stage is good at controlling the interconnect cable it stands a very good chance of being more neutral than a passive device and possibly also lower distortion, depending on the passive device to which its compared.
So its a mixed bag, which is why this conversation persists.
Such a keen point.
I n theory and on paper, the passive approach should be more invisible/transparent, more out of the way. Yet in practice, a high quality active will often yield the better or more realistic sound quality. It is indeed a “mixed bag.”
