Play-Fi supports a wide variety of file formats, including MP3, MP4A, AAC, FLAC, WAV and AIFF. In standard mode, which is optimised for multi-room bandwidth, audio is streamed at up to 16-bit/48kHz – akin to CD-quality. By engaging Play-Fi’s Critical Listening Mode, hi-res audio up to 24-bit/192kHz may be streamed to the Artera Solus Play over Wi-Fi or Ethernet cable, without transcoding or down-sampling.

There are other ways to stream music to the Artera Solus Play wirelessly, other than via the Play-Fi app. Spotify users can connect directly from the Spotify app thanks to Spotify Connect, and you can stream from smartphones and tablets without connecting to the local Wi-Fi network thanks to aptX Bluetooth.

Despite its attractive simplicity, the Artera Solus Play sports cutting-edge sophistication beneath the skin. At its heart nestles the ES9018 Sabre32 Reference, the eminent 32-bit, eight-channel hybrid multi-bit Delta-Sigma DAC chip, expertly implemented by Quad’s renowned electronics engineers. External sources benefit from this DAC’s exceptional quality via a range of digital inputs, handling PCM data up to 32-bit/384kHz as well as DSD64/128/256. This ensures the Artera Solus Play is equipped to make the most of today’s hi-res music formats, as well as future advances in ultra-high-definition digital sound.

For CD replay, a slot-loading mechanism buffers data from the disc before feeding it to the asynchronous DAC section. Four digital filter options enable users to tailor the sound from both CDs and external digital sources, to suit personal taste and the nature of the source material.

The discrete power amp circuits’ output stage uses a CFB (Complementary Feedback) topology in combination with conventional emitter follower circuitry. The CFB stage offers superior linearity and ensures excellent thermal stability, as the idle current is kept independent of the temperature of the output transistors. Using an emitter follower in combination with the CFB stage is an efficient way of increasing the current ability of the amplifier without compromising the advantages of the CFB circuit.

Having the emitter follower deliver additional current only when needed allows for a simpler current-limiting arrangement, which can be voltage-independent. Current limiting is under microprocessor control and programmed to allow the amplifier to supply high currents (+/- 15A) into complex loads, surpassing amplifiers that are bigger and more powerful on paper. A 300VA toroidal transformer supplies the two mono amplifiers using separate secondary windings, followed by 2x15000uF reservoir capacity per channel (60000uF in total).
