The PlayStream A7 is a connected amplifier. It delivers 115 watts per channel thanks to class AB amplification with High-Bias technology. It features an AKM AK4490 converter and offers extensive connectivity, including HDMI ARC. This device allows playback of traditional sources as well as access to streaming services.
Technical Architecture and High-Bias Technology
The PlayStream A7 is based on a class AB design enhanced by High-Bias technology. This approach increases the idle current of the output transistors, allowing the amplifier to operate in class A for the first few watts. In practice, when listening at moderate volume, the device behaves like a class A amplifier, with its advantages in linearity and low distortion.
At the heart of the device, an oversized toroidal transformer measuring 11.5 x 7 cm ensures stable power supply. Two 10,000 µF filter capacitors provide a substantial energy reserve. This robust power supply enables the high-precision transistors to deliver 115 watts per channel at 8 ohms, with distortion below 0.004% at 1 kHz. The frequency response ranges from 20 Hz to 80 kHz, demonstrating the circuit’s wide bandwidth.
The digital section is built around an AKM AK4490 converter paired with an AKM AK4118 selector. This combination allows processing of PCM streams up to 24-bit/192 kHz via coaxial and USB, or 24-bit/96 kHz via optical. The signal-to-noise ratio reaches 98 dB, ensuring a silent background even at high volume.
Extensive Connectivity and Network Integration
The PlayStream A7 stands out for its particularly rich connectivity. The rear panel features six RCA analog inputs, including a configurable phono input compatible with both MM and MC cartridges. Vinyl enthusiasts will appreciate this flexibility, which eliminates the need for an external phono preamplifier. An AMP IN input allows you to use only the amplification section, turning the device into a power amp.
The digital section includes three optical inputs and one coaxial, plus two USB ports for direct audio file playback. The HDMI ARC input is a major asset for integration into an audiovisual system, automatically retrieving the audio signal from a compatible TV.
Ethernet and Wi-Fi network modules provide access to streaming services: Spotify, Qobuz, Tidal, Deezer, TuneIn, iHeartRadio, vTuner, and Napster. DLNA compatibility allows playback of files stored on a computer, smartphone, or NAS server. The AirPlay protocol makes streaming from Apple devices easy. A dedicated connector accommodates optional Bluetooth modules X-FTB01 or X-FTB02, the latter supporting aptX HD.
The dual pair of binding posts accepts bare wire, banana plugs, and spades, allowing for bi-wiring. Two SUB outputs enable the addition of subwoofers, while a PRE OUT output allows pairing with an external power amplifier. An FM and DAB+ tuner completes the equipment, receiving both analog and digital stations.
Positioning Compared to the PlayStream A5
The PlayStream A7 shares many features with its sibling, the A5, while offering substantial improvements. Power increases from 80 to 115 watts per channel, providing more dynamic headroom and better control of demanding speakers. The AKM AK4490 DAC replaces a less sophisticated chip, improving resolution and channel separation.
The addition of the HDMI ARC port is the most visible difference, turning the A7 into a true hub for a home theater setup. The dual pair of binding posts, absent on the A5, allows for bi-wiring or connecting two pairs of speakers. These improvements justify the approximately 300-euro price difference between the two models.
Both devices share the High-Bias architecture, identical network connectivity, and the Advance control app. The choice between the A5 and A7 will mainly depend on the required power, the need for HDMI ARC, and the available budget.

Very beautiful and efficient amplifier made in France, the sound is very detailed and nicely powerful.
The only downsides after six years are the needles on the front panel, which have never worked properly, and the lack of updates anymore (the amp is no longer manufactured), which would notably make it possible to use Qobuz Connect.
Lastly, the Advance app is really minimalist and requires using another one.
So these are only aesthetic or convenience details that do not prevent you from fully enjoying its excellent sound quality.
You still need to pair it well with suitable speakers.
And on that point, I was once again able to rely on the advice and professionalism of the sales staff at the Compiègne store.
Thanks to them for the hours of listening!

Tres beau et efficace amplificateur made in France, le son est très détaillé et joli puissance.
Les seuls bémols au bout de six ans sont les aiguilles en façade qui n'ont jamais fonctionné correctement, et plus de mise à jour (ampli plus fabriqué) qui permettrait notamment de pouvoir utiliser Qobuz Connect.
Enfin l'appli Advance qui est vraiment minimaliste et qui nécessite d'en utiliser une autre.
Ce ne sont donc que des détails esthétiques ou de confort qui n'empêchent pas de profiter comme il se doit de son excellente sonorité.
Encore faut il bien l'associer à des enceintes adaptées.
Et la dessus, j'ai pu à nouveau compter sur les conseils et professionnalisme des vendeurs du magasin de Compiègne.
Merci à eux pour les heures d'écoute!
