The Estate Sale Goldmine
The market for vintage 1970s audio gear (like Marantz, Pioneer, and McIntosh) has exploded. Often, families clearing out estates list this heavy, high-end equipment on local classifieds for a fraction of its true value because they simply don't know what they have.

- Broad Keywords: Track generic terms like "old stereo" or "heavy silver radio" to catch listings from unknowledgeable sellers.
