With Lumin players (using AirPlay), you can also use Spotify app on iOS devices to remote control it from your couch. For CD-quality internet streaming, there are also Tidal and Qobuz, both are natively supported by Lumin app, or you can use AirPlay if you prefer the Tidal / Qobuz official apps. For Hi-Res quality streaming, Lumin will soon support full decoding of Tidal Masters MQA, and already support Qobuz Sublime+.
For playback of music files, after they are placed in NAS or L1, you can also remote control the playback of Lumin network players from your couch. In addition to convenience, there is an advantage of the elimination of computer from the music path. Normally-configured computers are not ideal devices for music playback, because the hardware creates lots of interference and signal noise that go through the USB cable to degrade the sound quality of your USB DAC. Therefore people using computer for music playback use all sorts of tricks (e.g. OS optimizer, fanless design, linear power supply, USB isolation, USB signal regeneration, etc.) to reduce the sound quality degradation. Some people also prefer not to have a computer in their music room.
