The 7 Greatest Integrated Amplifiers Ever Built — and Why You’ve Never Heard of Half of Them!

Discover seven of the best vintage integrated amplifiers ever made — and why these underrated classics deserve just as much attention as the legendary receivers.

In this video, we rank incredible vintage hi-fi integrated amps from Pioneer, Kenwood, McIntosh, Yamaha, Marantz, Sansui, and Accuphase. These amplifiers were built during the golden age of stereo, often using the same quality components, engineering, and craftsmanship found in the most famous receivers of the 1970s — but many still sell for a fraction of the price.

From the powerful Pioneer SA-9900 and underrated Kenwood KA-9100 to the iconic Sansui AU-20000 and legendary Accuphase E-202, we break down what makes each amplifier special, including build quality, power output, design, sound, reliability, and collectability.

Whether you are a vintage audio collector, hi-fi enthusiast, stereo repair fan, or just getting into classic audio gear, this list is packed with amplifiers worth knowing about.

Featured amplifiers include:
Accuphase E-202
Kenwood KA-9100
Marantz 1300DC
McIntosh MA6100
Pioneer SA-9900
Sansui AU-20000
Yamaha CA-2010
