Choosing the DAC

Both our CXA60 and CXA80 amplifiers employ the same Wolfson WM8740 DAC, and thereʼs a very good reason for that: it sounds superb! There are more recent Wolfson DACs in circulation, however none sound quite as great as the WM8740 in our view. Which is why, time and again, we choose them.

 

Two-into-one transformer

The CXA80 utilises two separate windings on the oversize toroidal transformer. In effect, this is like having two toroidal transformers wound onto one chassis, providing separate windings for each amplification module. If you get a huge transient in the right channel, it wonʼt unsettle whatʼs going on in the left. The current is being drawn from a different path, rather than a common path, so the output is stable and remains unflustered, whether your liking is for Little Richard or Lamb of God.

Dynamic Thermal Tracking transistors

The transistors used by the CXA80 are not your usual common or garden offerings. They come with an integrated Dynamic Thermal Tracking System. So what does this mean? Normally a Power Output transistor utilises 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 itʼs not a delayed heating effect. This enables us to bias the amplifier more accurately and in almost real time. Which means your CXA80 is always running at optimum performance.

Musical Subwoofer output

If you want to use a subwoofer as part of your speaker complement, the CXA80 doesnʼt penalise you for it. Because we want to ensure thereʼs no unnecessary high frequency noise affecting the subwoofer, weʼve 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.

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 minimise distortion in order to get the best results. This invariably meant 46 components sat in the signal path. For the CX Series, we wanted to dramatically reduce that component count. The CXA80 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. Previously, tweaking one of the 46 components only made a small difference and it was sometimes difficult to quantify exactly what difference any change made. With the CX series, those 24 components have now actually become quite critical. Changing just one affects the character of the amplifier.We can hear very clearly what each of those components is doing.

 

This revision has fundamentally changed the character of the amplifier. Listening to a CX series amplifier is fun, engaging and exciting.

High resolution asynchronous USB

In order to offer 24-bit 192kHz resolution via asynchronous USB we use a specialist XMOS device dedicated to the USB input. Weʼve also written a custom driver to allow PC users to access the higher sample rates available in USB Audio 2 mode. This bespoke code allows us to stream audio files at the highest possible resolution.

Bespoke Bluetooth

If you want to use your CXA80 with a Bluetooth source, we offer an optional BT100 audio receiver. To ensure that this does not interfere with other components in the amplifier, itʼs isolated internally on the digital input board. From the ground up, this is an audiophile Bluetooth device. 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 thereʼs a good reason to keep things uncomplicated. The CXA80 features a high-quality damped metal chassis, designed to ensure that nothing rattles or interferes with the electronics. Weʼve also kept volume control simple. The CXA80 uses a logarithmic ALPS pot. And when it comes to switching inputs, the CXA80 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.
