Cambridge CXA81 MK2: Unlocking High-Resolution Audio with Upgraded DAC

Cambridge amplifiers have long been celebrated for delivering exceptional value, offering high-end quality without the exorbitant price tag. The mid-tier CX series, in particular, stands out for its rich feature set and accessibility, making it an attractive option for discerning consumers on a budget.

Within the CX series of integrated amplifiers, the CXA61 and CXA81 models are the mainstays. The latter has been upgraded to a second-generation MK2 version, featuring an enhanced built-in DAC chip while upholding the Cambridge CX series' hallmark of versatility and outstanding cost-performance ratio.

Notably, Cambridge, a distinguished British audio brand, has chosen to remain committed to Class AB amplification, striking a harmonious balance between sonic fidelity and energy efficiency, rather than following the trend of Class D amplification. The CXA81 MK2 delivers a robust 80 watts per channel, powered by a custom-designed linear power supply with a substantial toroidal transformer. This configuration ensures ample power reserves, enabling the CXA81 MK2 to effortlessly drive typical home loudspeakers and reproduce the full dynamic range of music. Furthermore, it is equipped with two sets of speaker output terminals, offering the option of bi-wiring for compatible speakers.

In terms of analog inputs, the CXA81 MK2 provides a comprehensive array, including four RCA inputs and a balanced XLR input, which should readily satisfy most users' needs. For future system upgrades, pre-amp outputs and a subwoofer output are also available, offering considerable flexibility. For private listening sessions, a convenient 3.5mm headphone output jack is included, allowing you to enjoy music without disturbing others. Please share the article with me.

A wealth of connectivity options is a significant strength of the CXA81 MK2. While it may present itself as a straightforward and unassuming integrated amplifier, its capabilities are considerably more extensive than appearances suggest. Internally, the CXA81 MK2 incorporates an ES9018K2M DAC chip for digital-to-analog conversion (an upgrade from the ES9016K2M in the original CXA81). It features two optical inputs, one RCA coaxial input, and a USB Type-B input. The USB input offers the highest resolution support, handling PCM up to 24-bit/384kHz and DSD256, ensuring compatibility with high-resolution music formats.

For wireless convenience, Bluetooth input is also included, adhering to version 4.2 but with aptX and aptX HD codec support. When paired with compatible devices, this facilitates high-quality wireless audio streaming. Furthermore, the latest iteration, the CXA81 MK2, is designated as Roon Tested, enabling seamless integration as a Roon Bridge endpoint DAC within a Roon ecosystem. For those wishing to incorporate the amplifier into a home automation or control system, an RS232C port is readily available.
