ADD POWR X4, Apprentice and Symphony Pro’s

I believe after testing and using for six months the ADD X4 along with the Apprentice and several Symphony Pro’s for music and video I amazed at the improvements. My audio system as been transformed and my Sony 65” television has the best picture I have ever watch on this tv. In my own opinion these are a necessity to any high end system. The music sounds so real with detail and depth. You will not hear the potential of your system without them!
