How much is a breakout box? The entry price point on the latest geration of receivers that can pass through 4K HDR and deal with all the latest audio has come down significantly. I know 4K isn't a concern today with this setup but it may be in the future for you. Just a thought since you mentioned it earlier.

A box is pretty cheap, actually. You can get one for about $30 that I understand works reasonably well. At some point I am definitely going to replace the receiver. It will solve a number of problems, but for a couple of reasons not worth going into (other than the financial part) it doesn't really make sense for me to do it just yet.
