It makes a bit of a difference, in my experience. That's a very vague answer, and probably not very helpful, but it's a subjective judgement and will depend on how significant you generally find differences between components. For me, there's a clearly audible difference between some (but by no means all) streamers but I wouldn't call it a night-and-day, veils-were-lifted, soundstage-magically-became-3D type of difference. Other people, hearing the same changes, might if they're rather more excitable.
