With Volumio I found practical use for an old laptop. In fact I noticed that I don't need much more for music listening. With a decent DAC and Hi-Fi system connectd to the laptop I can enjoy technically high quality music. I can save my whole CD collection on the HDD of the laptop as well as listen to them, web radios and streaming services with a simple system. As long as I don't make own recordings, I only need a FM tuner for local broadcastings to listen to all possible music sources. If I can wish some improvements, first it would be nice to install Volumio 3 to a laptop, not necessary so old i now have. Secondly it would be nice, if the DVD drive of the laptop could be used for music uploading to Volumio (on the HDD of the laptop) and if the Wi-Fi connection of the laptop could be used for Internet connection. Now the last two features do not work. In any case I will also experiment how Volumio works on Raspberry Pi 4 - possibly for a music system for my summer house.
