Have you heard or own the Shakti Hallograph

I don't see much on the AudiogoN Forums about the Shakti Hallograph's. This is the BEST, a Five Star world class room treatment device...."it works" is an understatement.
It addresses,.. no "solves" the wall behind the speakers reflections and comb filtering distortion and cancellation.
A Wonderfull piece of Acoustic Engineering.
Simply Excellent and most Highly Recommended.
