Bose 901

My dad had 901's for a while, connected to a Marantz receiver. This was before the days that sound-staging became such a critical issue for stereo nuts, and the spacious sound that emanated from them was revelatory for this teen-aged audiophile.  It didn't hurt that the rig could really blast.

For me, the 901 Bose was a worthwhile way station on the path to high-end.
