Fortunately I'm pretty close to Jim’s home as well. Locating everything precisely, things were pretty close to start with, but refining those points paid dividends without a doubt.
His attention to detail regarding getting an even bass response as well as the correct setting of gain from the REL 212s cleared up the slight congestion remaining.
The way he adjusts things focusing on the voices was interesting.
Additionally, and this is a big deal, my wife loves it as well. A little afraid she's going to ask me how to turn it on.
