This has been an enjoyable thread.
At one time, I owned a Carver C-9 Sonic Hologram Generator, so the mention of the device brought a grin to my face. Bob Carver was quite a presence in the hi-fi world for decades and a great marketing guy (said with admiration). I loved his ad copy and probably got sucked into the Sonic Hologram by one of his dense ads. Anyway, the Sonic Hologram process was embedded in upper-end Carver preamps but I got my version as a stand-alone processor. As CAH mentioned, the process worked well on some songs but was not as profound on others. I well recall listening to CCR's "Suzie Q" and it cast a wide, wide stage. In the rawest of terms, it used digital processing to eliminate acoustical cross-talk; the effect was somewhat akin to wearing headphones.
In my opinion, having listened a lot (in the past) to music altered by Sonic Holography and having owned both the Devialet 180 (later a 200 virtue of a firmware upgrade) and my current Devialet Expert 220 Pro, the comparison is a non-starter. Again, this is my opinion but I can't find anything similar in what I recall hearing and what I hear today from my D220.
Now, if @rooze wants to have some fun, let him evaluate Sweet Room!
