The Cambridge Audio CXA61 amplifier boasts a sleek and contemporary design that is visually appealing. Constructed with a robust metal chassis and a thick aluminum front panel, it exudes quality. At the center, you’ll find the control and indicator section, while the multifunctional knob on the right enhances usability. This includes a prominent volume control knob utilizing an Alps variable resistor, alongside compact stereo balance and tone controls for both low and high frequencies. On the left side of the front panel, there is a headphone jack and an additional mini-jack input for portable devices. The amplifier also comes with a remote control for added convenience.
The Cambridge Audio CXA61 amplifier features a substantial audiophile-grade toroidal transformer, centrally positioned within its anti-resonance chassis. It operates in class A/B, which results in considerable heat generation in its output stages. To ensure optimal cooling, these stages are mounted on robust heat sinks, individually designed for the left and right channels. The CXA61 delivers a power output of 2 x 60 W at an 8-ohm load and 2 x 90 W with 4-ohm speakers, demonstrating its capability to handle high output currents. This allows the amplifier to effectively manage speakers with complex impedance characteristics. Additionally, the amplifier’s circuit is designed symmetrically to enhance stereo channel separation and reduce crosstalk.
The Cambridge Audio CXA61 features inputs for five linear signal sources, including four RCA connectors located on the rear panel and one 3.5 mm mini-jack on the front. Additionally, it offers optical and coaxial inputs. The device is equipped with a USB input that supports 32 / 384 kHz PCM and DSD256 formats, along with an RS232 connector and trigger inputs. Its built-in DAC utilizes the ESS Sabre SE9010K2M chip, capable of processing signals up to 24 bit / 192 kHz. Furthermore, the CXA61 includes a Bluetooth module that supports the aptX codec. Users can connect two pairs of speakers via reliable screw terminals, with selection managed through buttons on the front panel. The amplifier also provides a preamplifier output and a connection for an active subwoofer.
The Cambridge Audio CXA61 offers user-friendly operation. The buttons on the panel and the volume knob provide immediate feedback to your commands. The sturdy and thoughtfully designed remote control will soon become an essential tool for your audio experience. This remote is compatible with all models in the CX series. Additionally, the channel balance and tone controls function seamlessly. It is recommended to try the Direct mode, as it bypasses the tone circuitry for a purer sound.
The Cambridge Audio CXA61 immediately draws attention with its vibrant energy, smoothness, and an uncommon enthusiasm for music. Prioritizing listening enjoyment, this amplifier does not overlook the importance of detail, dynamics, or rhythmic accuracy; it effortlessly manages intricate compositions and subtle nuances. The iconic bassline of the White Stripes’ “Seven Nation Army” is delivered with tightness, groove, and power, instantly captivating the audience. The CXA61 adopts a straightforward approach that remains engaging rather than irritating. The guitar riffs resonate with texture and clarity, while Jack White’s raw and intense vocals are portrayed with depth. The performance is truly remarkable. The amplifier maintains a balanced energy, avoiding extremes, and exhibits exceptional control over dynamics and rhythms. In Hans Zimmer’s “Inception,” the soundscape is appropriately dark, creating a sense of tension. The strings in “Time” gradually swell, while the drums contribute to a feeling of desolation. The concluding piano notes linger in the expansive soundstage, their vibrant and enchanting tones leaving a lasting impression.
