- A11 has dual HDMI (one HDMI 2.0a video, one HDMI 1.4a audio).
- A11 has better quality internal PSU and internal shielding (although A10 is already excellent in this regard).
- A11 has internal wi-fi antennas rather than external (important in some enclosures).
- A11 wifi is 2.4G/5G 2T2R rather than 2.4G/5G.
- A11 has RS232 and IR cable inputs.
- A11 has front USB port.
- A11 has better (and 360 degree Bluetooth) remote.
Otherwise, they are the same. The firmware is basically identical.
