Cambridge Audio AXR100 vs Yamaha A-S501 Stereo Amplifier

The Cambridge Audio AXR100 is the stronger pick for most shoppers: it delivers a genuine 100W per channel into 8Ω, has Bluetooth built in, and adds a dedicated subwoofer output for a 2.1 setup. The Yamaha A-S501BL counters with a cleaner signal path (99dB S/N), a moving-magnet phono stage, and optical and coaxial digital inputs for a TV or disc player. Build is solid on both, but the Yamaha feels heavier and more substantial; owners of both praise their clean, punchy sound, and the Cambridge is the more flexible modern hub while the Yamaha suits vinyl and digital sources.

• Choose the Cambridge Audio AXR100 if you want built-in Bluetooth, a subwoofer output, and the most power per channel for driving less sensitive speakers.
• Choose the Yamaha A-S501BL if you play vinyl through a moving-magnet cartridge or want to connect a TV or Blu-ray player over optical or coaxial digital.
