For users with older legacy Naim equipment ( 1st Gen Mu-So & Mu-So Qb, Uniti, Uniti 2, Unitilite, Unitiqute, Unitiqute 2, Superuniti, NAC-N172, NAC-N272, ND5XS, NDX, NDS) reliant upon Vtuner for Internet radio service, while their service is not functioning, there are some other suggested ways you can try to get Internet radio to your devices;
If you have a current generation Naim streamer then you can use the multi-room feature to send IR to your older Naim devices.
For those with older Naim streaming devices that have Bluetooth, you can connect a Bluetooth enabled device such as a phone, tablet/iPad, or computer and use that to source IR and send to your older Naim device.
You can also connect an iPhone or iPad and use the iRadio App.
You can also connect directly to your device either by analogue or by digital s/pdif connection.
