No reason to go higher. USB 2.0 has plenty of bandwidth for audio, including DSD.
USB 2.0 has the widest compatibility as well.
To give you an example, a 384kHz/32 bit stereo audio signal only needs ~ 25 Mbps but USB 2.0 supports 480 Mbps
Why still USB 2.0?
I have noted many streamers , or int. amp still having USB 2.0 on their machine, especially the USB B socket.But form computer pov today is USB 3.0 or above dominant already, and type C plugs are widely abailable . Why the audio industry still prefer the USB 2.0?
