CAMBRIDGE AUDIO CXA81 MKII

The Cambridge CXA81 MK II is an integrated stereo amplifier capable of delivering 80 watts per channel in Class AB. It combines power, control, and exceptional detail, designed to reveal every musical nuance, whether streaming, playing CDs, or vinyl.

The CXA81 MK II belongs to Cambridge Audio's renewed CX Series, which also includes the more compact CXA61 amplifier, the CXC CD transport, and the CXN 100 network player. Each component is carefully selected and tested in Cambridge Audio's London laboratories to ensure the highest sound quality. The Class AB amplification circuit design blends the musicality of Class A with the efficiency of Class B. Additionally, the signal travels through an extremely short path within the circuits, minimizing interference and delivering pure, authentic sound, faithful to the emotional impact envisioned by the artist.

The CXA81 MK II is highly versatile, supporting numerous analog and digital inputs to connect CD players, streamers, PCs, and TVs. Furthermore, it features wireless connectivity through the aptX HD Bluetooth module, allowing compatible sources and even Bluetooth-integrated headphones to connect seamlessly.

The design of the CXA81 MK II is elegant and minimalist, using high-quality materials such as aluminum and steel for a refined aesthetic and robust construction.

The amplifier features a functional front panel with source selectors and a volume knob. All controls are also accessible via the included remote control, which is compatible with other devices in the CX Series.

The 3.5mm headphone output guarantees high-quality listening, while the analog and digital inputs allow you to connect any type of source.

The rear panel includes five analog inputs, including one balanced XLR and a 3.5mm jack input on the front panel for quick connections to smartphones or tablets. Digital inputs include a Toslink optical input, an SPDIF coaxial input, and a Hi-Res USB port.

The CXA81 MK II is equipped with an advanced ESS ES9018 K2M SABRE 32 DAC, capable of handling high-resolution digital audio files up to 32-bit/384kHz and DSD256, delivering outstanding performance for its price category.

The aptX HD Bluetooth module ensures a stable, high-quality wireless connection, supporting up to 24-bit/48kHz. For those seeking a more complete musical experience, Cambridge offers the CXN100 network player, ideal for accessing the world of high-resolution music.

For optimal performance, pairing it with KEF's Q Series or speakers like the renowned LS50 Meta, R3, or R5 is recommended. This ensures exceptional detail, a coherent soundstage, and precise instrumental reproduction.

Rock enthusiasts will find an ideal partner in Dynaudio's Emit Series, known for its impressive dynamics, transparency, and deep bass. The CXA81 MK II also performs admirably with higher-end models such as the Special Forty, Evoke 20, and Evoke 30.

The Sub output allows connection to an active subwoofer to enhance the listening experience. Recommended options include Cambridge's SX120 sub, KEF's Kube Series, or Dynaudio's Sub 3.

The CXA81 MK II supports speaker cables with any type of termination: spades, bananas, or bare wire. High-quality cables like Chord Company’s ClearwayX are recommended for excellent transparency and detail, along with Clearway interconnect cables designed to ensure optimal signal transmission while preventing electromagnetic (EMI) or radio frequency (RFI) interference.
