I think also that you grossly underestimate the Halcyonics for whatever reason.

Not true at all.
However, seeing your room and the hard surfaces that surround your components, I cushion your revelations with the belief that you could reap significant benefits through substantially less expensive measures.
Were you to treat your room with basic acoustic treatments, perhaps with the guidance of a professional such as Rives Audio (no relation...just comes immediately to mind), I suspect you would reap stunning benefits from your more esoteric tweaks. That's the bottom line.
I suspect you are accustomed to, and enjoy, the live, "bouncy" sound of your room, and subsequent adjustments improve what you hear in the present paradigm. I also suspect that traditional acoustic treatments likely shift the paradigm to something that's unfamiliar, less bouncy, and less enjoyable to you.
Thus enters YMMV.
