I see you've gotten no response. I have the 2.2 and I have been very happy with it. I was using Vandersteen 2 sig's which are pretty forgiving speakers. I'm now using maggie 3.6 speakers and they are supposed to be ruthless in showing the weakness of your components. I was worried that the 2.2 would fall short but it only sounds better, more detail, very smooth. I'm running mine direct to the amps. I have not heard the 2.0.
