On my tabletop system, I tried decoupling. It's a solid maple table with a 1.5" thick top. Part of the (my) reason for a table top system, was so that I could actually couple myself to the sound. I know a deaf person who does this to experience music in this way and that's where I learned it. With both senses available, this makes for a "stereo" sensory attack, especially with high impact music. I lean on the table with the music cranked. It will stone you to a condition of sensory intoxication that rivals deep meditation. I will listen for hrs like this, sitting in a regular chair.
While there is probably a million, scientific facts, as to why this tactic is an audio trainwreck, it is something I really enjoy doing. The near field aspect cancels most room issues, it doesn't take a whole lot of power, and can be set up in minutes. It also occurred to me that I had been coupled to my speakers for decades, since I mostly sat on the floor between them, where I could reach my system and EQ controls. This also allows me to get a louder music effect with less power, which helps when the urge to rock out hits at 2 AM, and you don't want to rock the neighbors.
