Want to enable my old Sony stereo to stream music from my Synology NAS.
The NAS doesn't have Bluetooth so wifi will be my preferred choice.
Best will be something small such as a pen or small card size that can plugged in to AUX port and can stream directly from NAS, with a integrated display so I can navigate trough NAS directories.
Second option having a external remote with display to navigate trough NAS and push music wireless to stereo using the unit plugged into AUX port.
Don't want big boxes around, I know I can find a lot of beautiful high end and complete AV media players, I just need one AUX output with wifi input and a display for remote control.
Also prefer not to use mobile applications such as iPad apps, want something all-in one or at least with a separate dedicated remote.
