Have you heard or own the Shakti Hallograph

Is it true the Hallographs have a crystal inside somewhere (like the Mpingo disc) or is that an old wives tale?

At one time I had two pair of Hallographs, having heard a very convincing demonstration I think at CES. There is no question, they work. But they need to be carefully adjusted and placed. One could literally focus the sound with them.

Although Syn. Res. recommended them with the ARTs devices, in my system the two were incompatible and I went with the ARTs. Basically, if I adjusted the ARTs to be right, the introduction of the Hallographs didn't sound right and were I to adjust the Hallograph to be right the introduction of the ARTs ruined the sound.

Both are now gone. I tried the Zilplexes and got the most realism I've heard even in a very small (13 x 10 x 8') room. I am ever mindful that others have different rooms and tastes.

I like my sticks. They are kool looking and add depth and realism to the sound. Having two more sets cloned to run on the sides and back of the room.

3 IPC Energizers are also in duty and it has a pretty positive strong effect on the sound. Two more coming so 5 will top out the IPC. The IPC EQ is the next try. Boat load of $$$ for the IPC EQ.

I have had Argent Room Lenses for years. Used 3 for sometime and then put one in hiding. I put it behind my chair this weekend to adjust the horizontal offset of the soundstage which had slightly more weight on the left side. If move the lens ever so slightly to the right of center then the room pressure is balanced. With the Lens 3 ft. behind my chair I can move it ever so slightly and really nail the focus coming from dead center. Great Product.

Also use a variation of an acoustic concept that Peter Israelson of Star Sound Technologies came up with. This device alters and focuses the soundstage and also can interject acoustic air where needed. This device can also be used to reduce bass standing waves along the floor an area that is usually left alone. I can augment the bass and focus the edges of the sound stage by changing their position as they lay on the floor. No foam no fiberglass only adjusting the air flow in my room. Like a wing. Tom

The Hallographs work, guys, and if you haven't tried them, and are commenting on them without empirical evidence...well, stay out of the line of detective work (my field).
The price? Well, look, if people can charge $15k for speaker cable and some of the prices for these speakers, why are these devices getting your dander up?
I had them a couple of years ago and they did exactly as they were advertised to do. I would've kept them, but Connecticut got two enormous (28") snowstorms two weeks apart and the ceiling cracked, so I had to repair it and returned the Hallographs.
I also agree they must be carefully placed, but that's no different than Tube Traps, where as little as 1/32" turn can lessen ambience and transients as well. Room acoustics are very complicated, but I doubt HP put these in his Editors Choice for the fun of it.
Are they really up to $1,700 now?!?! Jesus! They were $1100 back in the beginning of 2011.
