Brad ,I wanted to get back to you about whats going on with the Zero`s in my system, Shit this is great . The amps seem to like the 2.75x taps on the Zero`s driving my Innersound Isis , the speakers already had great imaging ,but now there even better. The resolution is much better as well, I`ve heard more from this setup than I have ever heard before, small details are now much easier hear. You don`t have to strain to hear them, dynamics are much better as well. I have played the drums for 35 plus years, and they sound more real , more like the wood that they are. The drums have more of there own space between them than before, all the instruments now are easier to follow and each has its own place in the sound field. the bass tighten up alot, pitch is better on the lower end than before. I beleive you should look in to these as and up grade to your present system, mine are keepers. Greg
