One of the best purchases I've ever made. I always thought I just had component compatibility problems or bad cables and kept selling everything. Once I installed the ground zero, the hum disappeared and my system sounded so much better all the way around. It's a bit challenging to figure out but well worth the effort.
granite audio ground zero
anyone have any thoughts or experiences with this product? my hum is driving me nuts.
