I am waaay behind in this scene but am looking to replace my aging Vu+ Duo2 which is pretty slow navigating menu's these days.

I'm hoping someone could save me hours of research and tell me what is considered to the the fastest Enigma2 receiver these days.

It must...
-Have a terrestrial tuner
-Have a decent processor capable of playing HD and 4K smoothly.
-Something smaller than the Duo2 would be a huge bonus. That thing is a unit!
