Handymann,
The issue with Wilsons disappering or not or any speaker disappearing or not has as much to do with preserving time and phase differences through the electronics.
Krell amplifiers tend to sound flat, clean but flat. Good bass and plenty of drive.
I used to shock people at my Sound by Singer days of using a tube preamp in front of the Krells which was considered taboo, and boy did it make the Krell's sound improve a lot.
I know you say you have a good sound stage, and you say you have good center fill, when you say the speakers are not dispearing does that mean you are not being drawn into the complete illusion of sounding live?
I would have you look at not just the room treatment and positioning but at the cables, power conditioning. the dac preamp etc.
Often times older components tend to lack the transparency of more modern products, so to me if a system is doing what you say it is doing then I would look at the rest of the chain.
Often upgrading to a more modern dac and bingo the sound tends to get much more palpable.
Our sound room uses echo busters and Shakti holographs, along with Acoustic System resonators these things are amazing and can really help with issues that you are describing.
