Good job. Not many people make the changes that we suggest. You did it eagerly and willingly. *High-5! If you keep experimenting with your set up and you get an improvement in your experience, we are all happy!
I'm gonna be the blasphemer here and say: If you wanna keep your AV gear separate from your TV, go right ahead.
Pogre's heart is in the right place. And I do agree.
But I'm also comfortable stepping back and letting you decide your next steps.
Remember we are here and willing to help. Especially when it comes to other people's money!
Cheers.
