  • THE HEART OF YOUR DIGITAL MUSIC SYSTEM

    Rated at 60 Watts per channel this class AB amplifier design will reveal spectacular detail in your music. Low-flux toroidal transformer further enhance performance and design details deliver incredible control over your speakers.

    POWER PRECISION AND DIGITAL CONNECTIVITY

    To journey deeper into the music you love, the CXA60 has been designed with built-in digital to analog conversion capabilities. Using a high-specification 24-bit/192kHz DAC chip from Wolfson, the CXA60 offers a powerful upgrade for all your digital sources.

    CAREFUL POSITIONING

    We mount the premium transformer centrally, to reduce flux or magnetic disturbance from the volume pot.

    TOROIDAL TRANSFORMER

    Class AB amplifier design, a centrally mounted audiophile grade oversize toroidal transformer, and substantial extruded heatsinks allows the amp to deliver 2 x 60 Watts RMS into 8 Ohms. Into 4 Ohms, this increases to 2 x 90W.

    SUPERB SEPARATION

    The internal PCB layout is optimized for minimal left/right 'crosstalk' and to maximize the quality of stereo separation. By using symmetrical and separated circuit paths for the two channels, we ensure that it delivers stunning stereo separation and minimum cross-channel interference.

    DYNAMIC THERMAL TRACKING TRANSISTORS

    The transistors used by the CXA60 come with an integrated Dynamic Thermal Tracking System. Normally a Power Output transistor utilizes a thermo-coupler attached directly to the heat sink of the amp; this informs the system so that it can rebias when key temperatures are reached. However, using Integrated Dynamic Thermal tracking provides a far more accurate reading of the real temperature of a transistor, and relays it faster too because it’s not a delayed heating effect. This enables us to bias the amplifier more accurately and in almost real time.

    MUSICAL SUBWOOFER OUTPUT

    Because we want to ensure there’s no unnecessary high frequency noise affecting the subwoofer, we’ve put the output filter at 3KHz. This is high enough to prevent any phase shift associated with the low pass filter affecting what happens below 200Hz. The result is a phase linear subwoofer output signal which is clean and musical.

    FULLY BALANCED SIGNAL MANAGEMENT

    For the first time, our engineers decided to go fully balanced rather than single-ended all the way through. As a consequence, any noise that that might be picked up in the audio signal while routing through the amplifier is cancelled before its output.

    REINVENTING THE SIGNAL PATH

    The CX range represents a step change in the way our engineers have approached signal path design, and the result is one of our most musical and entertaining amplifiers yet. Previously, we went to almost surgical lengths to minimize distortion in order to get the best results. This invariably meant 46 components sat in the signal path. The CXA60 now has only 24 components in the signal path. The big difference is that there are now 500 support components as well. Their job is to guarantee those 24 key components are absolutely optimal all the time, regardless of mains fluctuations and other influences. This has made a big difference when it comes to tuning and you can hear very clearly what each of those components is doing.

    BESPOKE BLUETOOTH

    If you want to use your CXA60 with a Bluetooth source, we offer an optional BT100 audio receiver. To ensure that this does not interfere with other components in the amplifier, it’s isolated internally on the digital input board. All the coding for the BT100, including the aptX implementation, is done in-house. We even include an extension cable which enables you get the best Bluetooth range.

    EMBRACING CLASSIC DESIGN
    Sometimes there’s a good reason to keep things uncomplicated. The CXA60 features a high-quality damped metal chassis, designed to ensure that nothing rattles or interferes with the electronics. We’ve also kept volume control simple. The CXA60 uses a logarithmic ALPS pot. And when it comes to switching inputs, it uses relay switching with silver plated contacts. This classic approach is still the best way to move signals around, rather than with transistors or electronic switches.
