Acoustic Revive RR-77 Ultra low pulse generator

I bought a nice shelf set at Lowe's Home Improvement. The shelf is beveled and has a nice walnut finish. There are no visable wall brackets so it looks like a custom installation. Visually quite nice. Yes the King Rex is an upgrade and having the longer cable allows the PSU to sit on the floor. I think for most people the King Rex mark I unit will be just fine and that the mark II unit is not necessary.

In my experience the Acoustic Revive has it's best effect at 6.5 to 7.5 feet above the ground and centered on the wall behind the speakers. A second unit can be used behind the listener if it is also mid speaker positioned and at the same height as the front wall unit. Units that are not mid positioned can have a mixed bag effect-I have tried various positions and heights. I purchased my King Rex PSU from Audio Magnus in Canada. He also has the power cords for sale that are longer than the stock cords so the PSU can sit on the floor. I found this to be a worthwhile addition to my system.
