My last great Onk ever built is flawless! It detects formats from my PS3 and Firestick 4K. I am also able to configure the channel format I want on a per-source basis such that, for example, if a stereo signal is detected, it will auto-switch to PLII or Neo.
There are no funny clicks, pops or farts. It is rock solid. I will never let go of that Onk until it goes up in flames. Even then, I will dawn my fire suit, douse the flames, and using my vast skills, restore it to its former glory!
