Z11?
I am sure that all those are great products but why the Z11 if is not been review yet? Don't get me wrong it may be one of the best receivers out there, but I thought these awards are base in objective results and no just specifications. For example, base on some reviews the Onkyo 805 can output 128 watts rms x7 , and the Yamaha 1800 only 55 watts rms x 7, and these are similar priced products with similar specifications.(I know power is not everything, but if someone is looking for an upgrade of for example 60 rms receiver I think that information will help) But if you already have a review unit and made some tests, I thinck that will explain your selection.
