Only sounds of reason in here. For everyone, please, no matter what you think, at least give them a listen in YOUR system and then you will know if they do anything for you.

When I first saw these devices, I thought they'd be used in the first reflection as they would appear to breakup the first reflection if positioned in that area of each sidewall. GIK and others do this with room treatment.

I do not own these, and never plan to. But experience with them is the only way to know if they really work in your room or not.

Shakti did obtain a patent on the stone but I can locate nothing for the Hallograph. Patents are not cheap..if you hire an agent or a patent attorney. The fees are cheap for a small entity. Tom

PS Audio Noise Harvester. I know it's snake oil but I still bought one! The blue flashing LED did show me which dimmer switches were making the most noise, but made absolutely no difference in the sound of my system. I think Paul invented it for a joke just to see how many suckers he could reel in!

I think it would cost more to keep a patent pending for 17 years given than it would cost to simply file it.  I am guessing that patent application is long since not pending.

In descending order of ridiculousness, proportional to its price:

- cable lifters
- boutique fuses
- power cables
- digital cables
