PIONEER A-40AE-B, Intergraded amplifier, 2×60 Watt, Phono, BLACK

Features

The latest integrated amplifier from Pioneer created under the original Direct Energy concept incorporates the newly developed Direct Energy Design, pursuing high S/N ratio to create an overwhelming and life-like sound field.
With features including isolated power supply, custom-made large capacitors, Direct Function, Power Amp Direct Mode, aluminium volume knob/front panel, and phono MM input, you can enjoy crisp, clear sound just as intended by the artists.

Pioneer’s Direct Energy Design is based on the Direct Energy Concept—lossless transfer of energy from the amplifier to the speakers. Inheriting this philosophy, the latest integrated amplifiers feature optimised power supply/output circuit blocks, as well as parts layout. The result is excellent signal transfer and high S/N ratio.
Additionally, the A-40AE adopts the newly developed Direct Energy Construction, which supplies power to the substrate by layering a separate substrate for the shortest possible power supply path via wire. This is because wires have inductance components and are likely to cause noise. With this significant revision, signal loss and noise can be further reduced to deliver audio with a wide sound field and clear sound image.

The windings for the power amplifier, pre-amplifier, and controls are each separated inside the power transformer to prevent mutual noise interference.

The main capacitor, which determines an amplifier’s audio quality, was developed in collaboration with ELNA. The Pioneer logo on the sleeve shows that it is an exclusive pure audio capacitor.

The A-40AE features Direct Function, which bypasses other circuits except for the volume to offer a pure listening experience suitable for musical content. The function is not just a simple switching, but is finely tuned to enhance the musicality.

With the power amp direct terminal, you can connect an external pre-amplifier, and use the component as a power amplifier in a multichannel setup.

The Anti-Standing Wave Insulator features a special form with no parallel sides inside to prevent cavity resonance. This makes the sound localisation, tone, and scale clearer,while also contributing to seamless connection between the channels and improved response to quick sound.

The speaker terminals use non-magnetic material, which is less susceptible to external noise, and transmits signals to the speakers at high purity. The A-40AE is equipped with two sets of speaker outputs (A, B) that can be used individually or in parallel, as well as transparent high-grade speaker terminals for a reliable connection.

The A-40AE is equipped with a phono input (MM) terminal, letting you connect a turntable for enjoying quality audio performance from vinyl records.

The optical and coaxial digital inputs let you connect your TV or other audio players and enjoy quality sound. Hi-Res Audio is also supported, with the capacity to process up to 192 kHz sampling rates.

The A-40AE features an aluminium volume knob with a solid, highgrade feel and style. The simple aluminium front panel also adds a touch of elegance to the audio experience.

The integrated amplifier automatically switches to standby mode after 20 minutes of no audio input or operation.

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.

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.

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.

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.

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.

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.

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.

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.
