A second sub will probably improve things the most.
You're in luck, they have one left:

Apologies. So Toole, Olive and Geddes are the spiritual leaders of this thread?

One other thing. I found that my panel's ETC measured a little better when slightly separated. So, instead of 12' of contiguous panels the panels have a 10" gap between them. More gap or less gap was worse.

You seem to be sitting pretty far away from the screen. How large is that screen? And the distance to the left and right speakers could be closer to the equilateral triangle if you move the couch forward.
Here are a couple pictures of my our family room that I posted before on the other thread. Till a month ago this used to be what we called the "mud room." My wife's happy to have the TV/speakers out of the living room, and I'm sure happy to be able to crank my music after the kids go to be since I'm now on the opposite side of the house.





The pictures were taken before I put up 2' x 3' 4" absorption panels on either side of the couch as well as the clouds. I also put heavier polyester blackout curtains up. Come to think of it, I should measure the ETC with the curtains open and closed to see if this really made any difference. My ears tell me a little.

I will try moving the couch up, but it would be a awkward to do this more than a foot. I know it is not considered great to have the couch so close to the wall. I may actually consider putting a panel behind the curtains in font of the window. I will measure this. Assuming the ETC is what to look at here? My main thought though is still to build two 2' x 4' 4" absorption panels on either side of the back wall. I will try angling them out a bit to create the air pocket back there. Or I also am considering framing them with a 6" width wood so a air pocket will be created that way. Not sure if that's enough space to do much good.

The way I'm thinking now, I will most likely look at another PB-1000 sub in the next few months. Seems most people here think this will make the most difference, which makes sense to me. My only hesitation is that the corner to the right seems to be such a crappy place to put a sub that I do wonder if this could be counterproductive. Still, my thinking is that this would make more of a difference to SQ than moving to XT32. (Of course I'm sure some people might look at that picture and think I'm out of my mind to consider a second sub with a TV that old, but hey, I'm more of a music guy than movie. A new TV will come too.)

This week I will definitely try out the blocking technique when I spare moment. Thanks for that, Jerry. And thank you to everyone who has helped me here.

One of the many nice things about SVS is that you can try it and return it if it doesn't work out.
Instead of replacing your AVR, you might want to add a parametric equalizer to the subwoofer output. I used to use this one:

Should still be available used at Guitar Center and other places.

Would that work well used in addition to Audyssey XT? That link isn't working for me for some reason.

Yes. You need the other EQ for the other speakers; this just goes to the subs.
Here's one:

Dunno if this posting by Dr. Olive has been mentioned here:

A Method For Training Listeners and Selecting Program For Listening Tests

Listener Performance Is Strongly Influenced by Program SelectionThe single largest effect on the listener’s performance was the program selection. Slide 13 plots the mean listener performance scores for each of the twenty programs averaged across all eight equalizations. The percentage of correct responses ranged from a high of 88% (pink noise) to a low of 54% (jazz piano trio). Listeners performed the task best when using broadband, spectrally dense continuous signals like pink noise or pop/rock selections like Tracy Chapman, Little Feat, and Jennifer Warnes. Listeners performed worse on programs featuring solo instruments, small combos and speech that produced more discontinuous and narrow band signals. More about this later.
