Cambridge Audio makes amplifiers across three series — AX entry integrated, CX mid-range integrated, and EVO all-in-one streaming — plus the AXR100 stereo receiver. Specifically, each series targets a different listener profile. The price difference between an AXA25 and an EVO 150 reflects genuinely different capabilities, not specification inflation. This guide explains what each series does and who each model suits. The goal is to help you choose without overspending on features that do not match the intended use. For listeners who have already identified a bookshelf speaker, our best amplifiers for bookshelf speakers guide maps specific amplifier pairings at each budget.

  • Entry integrated — wired sources: AXA25 or AXA35 — phono stage, clean circuit, no streaming
  • Mid-range integrated — DAC + Bluetooth: CXA61 or CXA81 MkII — ESS Sabre DAC, apt-X HD, balanced outputs on CXA81
  • All-in-one streaming: EVO 75 or EVO 150 — AirPlay 2, Chromecast, HDMI ARC, no separate components needed
  • Receiver with tuner: AXR100 — FM/AM, Bluetooth, phono, 100W, Amazon’s Overall Pick

Cambridge Audio has held the same position since the 1960s — transparent, accurate amplification that undercuts the audiophile establishment without compromising circuit engineering. Specifically, their amplifiers are not designed to flatter recordings or add warmth. Instead, they are designed to communicate what is on the recording as accurately as the price point allows. Consequently, they suit listeners who value hearing the recording rather than hearing the amplifier.

Class XD — the CX series circuit

Cambridge Audio’s Class XD is a proprietary amplifier topology used in the CX series. Specifically, it works by displacing the crossover point away from zero — where class-A/B amplifiers transition between positive and negative output transistors. This crossover transition is where conventional class-A/B designs introduce a small but measurable distortion. Class XD moves this transition into a region where
