What does Holographic mean to you?

All the above plus, it means to me also the holographic belt of my turntable--very cool!

Something from Star Trek and Star Wars.

That the person using it doesn't do audio in the same vein as me, i.e. nothing.

Yes, kinda like a mini-Princess Leia is floating between your speakers saying "help me Fatparrot..."

Although with me, I've got Maria Grazia Cucinotta or Sophia Loren floating in front of me saying, "get off your lazy culo and put that green slanted head to use."

It means that the 2-channel set-up is so good that there
is no need to even think about surround sound.
