The Marantz Model 500 is vintage solid-state at its most unapologetically overbuilt—massive power, massive heat sinks, and the kind of old-school presence that instantly tells you this thing means business. Professionally restored, this example brings all that legendary muscle back to life with the smooth, authoritative sound that made the Model 500 such a statement piece in the golden age of hi-fi. It delivers effortless drive and deep, controlled bass, but there’s also a surprising warmth and musicality underneath all that power that keeps it from sounding sterile or overly aggressive. Equal parts brute force and vintage charm, it’s the kind of amplifier that anchors a system both sonically and visually the moment it lands in the rack.

- The History of Marantz
- More than any other person, Saul Marantz defined premium home entertainment. Driven by his passion for music and his accomplishments as a classical guitarist – accomplishments that led to a close friendship with Andres Segovia – he was never satisfied with the “hi fi” equipment of his day.

- Liner Notes
- The Marantz Model 500 Stereo Power Amplifier is vintage solid-state at its most unapologetically overbuilt—massive power, massive heat sinks, and the kind of old-school presence that instantly tells you this thing means business. Professionally restored, this example brings all that legendary muscle back to life with the smooth, authoritative sound that made the Model 500 such a statement piece in the golden age of hi-fi. Originally introduced as Marantz’s flagship “high-power machine” developed to pursue ultra-low distortion and massive dynamic capability, the Model 500 delivers effortless drive, deep controlled bass, and a surprising amount of warmth and musicality beneath all that brute force. Equal parts powerhouse and collectible icon, it’s the kind of amplifier that anchors a system both sonically and visually the moment it lands in the rack.
- Shipping
- To ensure safe arrival, we often use private couriers. These are transporters in Sprinter Vans or pulling covered trailers often moving art and antiques across the country. Absolutely the safest way to ship short of you picking it up yourself. This piece ships to the contiguous United States for a flat rate of $300, which includes our packaging and our insurance. Of course, we'll ship anywhere in the world, just drop us a line and we'll give you an estimate – even if you're just curious.
