Volumio is a great sound quality player and offers many DAC options and configurable settings. I used it with Raspberry Pi and iOS platforms. The interface is brilliant, instinctive and the look-and-feel makes this product a serious competitor for any other player in the market. Unfortunately, I'm sometimes facing some issues with the WiFi connection to network (need to reboot hardware) and this with many Raspberry Pi boards tried. Also, I need to erase and flash my SD card again at least one time every 3-4 months (16Go Classe-10 preferred) without any reason and even by proceeding every time with a proper shutdown sequence. What could be improved on RPi are the reliability/startup/self-repairing methods and perhaps to provide more compatibility with different hardware, especially TFT displays where it becomes a nightmare configuring the touchscreen except for the 7" TFT official. Nevertheless, I used it for many years and can't find any equivalent in the segment. Only Rune Audio was quite close from Volumio and seemed more reliable but unfortunately discarded and not maintained.
