Shanling EM5 Streaming Music Centre is offering access to main streaming services, DLNA, Airplay, Bluetooth and local playback. All controlled through the touch screen on top of the device or via app on your phone or tablet. EM5 is designed as a DAC/AMP for high-end headphones, with a range of different connectors, including balanced XLR and 4.4 mm. It can also be used as a DAC and pre-amplifier when combined with a separate power amplifier or active speakers. On the other hand, EM5 is working as an all-in-one streamer. While it lacks the balanced outputs and offers just a single ended headphone output, it adds in a full integrated amplifier, so it can be used directly to power your speaker system. ℹ️ Message for questions #highendaudio #headphoneamp #headphones #audiophile #headfi #dac #hifi #hifidelity #usbdac #audio #audioporn #hifiaudio #hifisound #hifiporn #airplay #spotify #amplifier #amplifiers #amplifierart #tubeamplifier #poweramplifier #preamplifier
