YEs, but the question is, why?
I can see how the proper eletronic mating might be trickier with a passive, but I cant see a disadvantage if done right
I can't see sound waves either, yet they are there. My ears tell me the difference, not my eyes. I can't explain why anymore than I can explain why a power cord can make a difference, or tubes sound better to me than solid state.
I'm sure that someone can probably come up with some techno-marketing buzz words that may help you understand why, but in the end, all the proof you should need is in the listening. Trust your own ears.
