ONKYO TX-8220-S Stereo AMP 100W / Channel, 6Ohm, Phono Input, BLUETOOTH, Silver

Add Dynamic Hi-Fi Sound to Your Entertainment Mix

Delivering 110 W/Ch of high-current power from a fully discrete low-impedance amplification system, the TX-8130 plays your audio sources with dynamic energy and pure musicality. Custom-spec components are used throughout, from high-current EI transformer, twin 8,200 μF capacitors, and rigid oval chassis to the 384 kHz/32-bit DAC that decodes Hi-Res 192/24 and 5.6 MHz DSD files streamed over the network.

Whether enjoying Spotify, Deezer, or TuneIn Radio (with song selection handled via remote app) or kicking back with a stack of LPs, listeners are rewarded with lush, detailed, and deeply satisfying sound that few amps at this price can equal. Other details such as BGM presets for one-touch playback of AM/FM/Internet Radio stations, generous analog/digital connectivity, and rock-solid build will confirm your impression of quality, value, and versatility.

Toroidal Transformer

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

The output power transistors used by the CXA60 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 re-bias 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 CXA60 is always running at optimum performance.

If you want to use a subwoofer as part of your speaker complement, the CXA60 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.

Thereʼs some revolutionary signal management happening beneath the lid of the CXA60. 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 itʼs output.

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 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. 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.

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, itʼs isolated internally on the digital input board. From the ground up, this is an audiophile Bluetooth device. All the coding for the BT100 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 CXA60 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 CXA60 uses a logarithmic ALPS pot. And when it comes to switching inputs, the CXA60 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.

Denon is one of the rare audio brands that continued to actively develop Hi-Fi components and accumulate, refine, and pass down Hi-Fi audio technologies. The 2500NE series, designed for todayʼs age, has been developed by both veteran engineers and talented young engineers who have inherited the Denon technologies and expertise that have been cultivated over many years and decades. And the performance of the PMA-2500NE goes well beyond that of Denonʼs previous PMA-2000 series. With its ultimate built-quality, unique Denon technologies and state-of-the-art connectivity, the PMA-2500NE truly is a masterpiece of sound technology. Thanks to the rear USB-B input and embedded high quality D/A converter, the PMA plays high resolution files up to 384kHz/32bit and DSD up to 11.2MHz from a computer in impeccable sonic quality. For the best performance from analogue inputs, the PMA features an Analog Mode which allows to switch off all unutilized sections like the digital input circuitry or the low noise display for an unaltered audio reproduction.
