A thought experiment example: vintage inspired looking speakers with a true horn and compression driver not some cheap cone tweeter. A powerful integrated with bass mangment, a remote and phono stage, a real subwoofer that will have more low bass output than a dozen of those vintage pioneers combined. Will play loud enough to damage your hearing in most rooms, since the speakers will be relieved of thier LF duties.

Just an example for fun. You really have to be cautious reading vintage enthusiast sites like autokarma. I like old stuff I have old stuff but new is higher performance.
