Debatable. 3D Printing could conceivably print circuit traces, but robots already do that and also install components in them. Since the best audio is usually obtained with point-to-point wiring and non-strip-feed components, anything you could do with 3D would probably be more along the lines of consumer audio than the "high-end".
It's possible that you could build PC boards with embedded resistors and capacitors, along with curved traces of solid silver, but why? You wouldn't be able to replace a component that failed. You'd have to replace the whole board,
The only thing I can see being 3D printed is perhaps a speaker enclosure. And it would probably be more expensive and not as sturdy as conventional methods. Even casting them out of ceramic or concrete would be better.
