Shakti Hallograph
Just wanted to throw in my 2 cents and say that the Hallograph work as described and to a remarkable degree. After reading so many reviews both pro and con I finally purchased a pair of the Hallograph arrays. By toeing the arrays both in and out the effect was quite like adjusting the bass and treble on a preamp. People complain about the cost but then turn around and pay big coin on other components. Room treatment is as important a parameter as line conditioning, cabling, vibration isolation, etc.
