Plays it all beautifully

Minx Xi isn't just about getting your audio from any device and having every connection, it's also about making sure that every piece of music sounds brilliant. Every source, whether connected physically or wirelessly, sounds great through Minx Xi. That's because we've used our decades of audio expertise and streaming expertise inside it.

The Class AB amplifier, oversized toroidal power supply and Wolfson WM8728 digital-analogue converter are audiophile components commonly found in high-end products – as is the external clocking we use to reduce jitter in digital audio transmission. This kind of kit is exceedingly rare in this kind of hi-fi. That's why we think Minx Xi is an absolutely brilliant system, not just for its connectivity and its classy looks, but for the audio quality you hear.

The end result is not just room-filling power  but also stunning detail drawn from all sources. However you like your music, Minx Xi will make it sound wonderful.

The perfect connection

Minx Xi isn't just wonderful at wireless audio – it's got plenty of sockets too. Extensive inputs include twoUSB ports that will also charge your smartphone or tablet , two digital inputs for set-top boxes, consoles, Blu-ray players and more, as well as three analogue inputs for CD players and other devices and even a subwoofer output and ethernet socket – making Minx Xi an ideal centre to an entertainment system.


Audiophile components – It's rare to see the kind of components found in Minx Xi in this kind of wireless designer system. But we believe that good looks should go hand in hand with great sound. Minx Xi features a high-quality 24-bit/96kHz Wolfson WM8728 DAC that means all sources are delivered in sparkling detail; an oversized toroidal power supply for improved audio quality and bass performance across the volume range; Class AB amplifier for great sound, low distortion and superb power efficiency; external clocking taken from our high-end NP30 network player to minimise jitter in digital audio streams

Digital and wireless – Wi-fi and Bluetooth wireless connections ensure every smartphone, tablet or wireless device will work with Minx Xi. And digital support is comprehensive including support for a wide array of digital audio formats (including lossless - FLAC, ALAC, AIFF, WAV supported via UPnP up to 24/96), physical digital audio connections and in-built support for many streaming services including BBC iPlayer Radio, Pandora and Rhapsody*. Plus firmware updates can be pushed to Minx Xi, ensuring it will continue to work with the latest internet services, apps and protocols

Physical and analogue – As well as widespread wireless support, the Minx Xi doesn't skimp on traditional analogue and physical connections. Two digital audio and three analogue audio inputs to turn the Minx Xi into the core of a home entertainment hub and three device-charging USBs are joined by a subwoofer out connection to turn the Minx Xi into a compact and stylish 2.1 system, Ethernet connection and pre-amp connection.
