In this video, I dive deep into the world of vintage stereo equipment, testing amplifiers and receivers paired with the notorious Infinity RS 1.5 speakers—often called “amp killers” for their low-impedance demands. After days of A/B testing nearly everything on the Skylabs Wall of Sound, I discovered some surprising insights about specs, synergy, and real-world performance.
Key highlights:
The Kenwood KR-2120: Surprisingly resilient despite being only 10W per channel.
Why power ratings and speaker specs don’t always tell the full story.
The Pioneer SX-727: A bass-heavy standout that redefined my view of Pioneer’s classic series.
Surprises from the Sansui 8080, Marantz 2220B, and others.
What makes the Concept 5.5 and Advance Paris A10 unforgettable performers.
The role of loudness controls and how they vary drastically between brands.
Whether you’re a casual listener or an audiophile chasing the perfect sound, this video has something for you! Plus, tips on why “living with your gear” matters more than obsessing over specs.
