@zuangbro - You really have me intrigued with your Radian 475be upgrade. I'm thinking of making the same leap with my Omen DWs. I recently replaced the Clarity caps with Duelund tinned copper caps (I know, I know, it was one of those what-the-heck shelter-in-place moments) and the Omens took on a whole new presence and holography. So that got me thinking, and googling, and here I am...
Would you do anything different with the resistor values you mentioned? Any regrets with the 475be? Any other mod updates?
