I got rid of the Synergetic Research TOL Powercell to get this one. I got to hear Garth's prototype along with the prototype cords a few years ago. I was blown away. The difference between this and the top 7000 is there, but not that large. This is a steal in the world of wanting great electrical for your gear. Try and get a Thunder cord for it also. It will lower the noise floor tremendously and give a much clearer picture into the music. It just gets out of the way and feeds your gear clean power. IT's as good as what's out there and under 5k, you will be hard pressed to do better in most situations. Remember that all rooms have different electrical needs.
