I’m considering buying some Neumann KH 310 A’s and will need a hub. I’m currently using a MacMini a CD player and an iPhone for Bluetooth as sources. Budget is around $500. Sound quality is most important. I don’t have wifi in my area so I’m relegated to Bluetooth. It’s convenient but not the best sound. A volume control, remote and xlr output are also necessary. I thought maybe minidsp? Not sure which one. Suggestions please
