So even a good tablet with 2 3 usb (one for lan one for digital export can be enough) or i am gonna loose quality due to usb?
Should i absolutely need laptop?
For example i got an ipad air where i can use ethernet but then i got no other usb... so i need a tablet with 2 usb at least and i am pretty sure there are many around
You said you were anti WiFi. Tablets are normally WiFi, but you could connect a USB to Ethernet adapter and disable WiFi. The problem with tablets is that it may be difficult to get bit-perfect playback from certain apps like Spotify and Tidal out to an external DAC with the price of slight potential quality loss. If you don't care then a tablet may do but you'll need a USB hub as you want to avoid wireless, so would need 2 USB devices connected to the tablet: a network adapter and a DAC.
