I just received this new Yamaha and have had very little time to get to know it really well. However, for those who may have an interest I would like to post a few observations. First the not so "hot" feature: The Remote...for me this is not the greatest new feature. Although very powerful it is difficult to read in either light or darkness. The backlight seems very inadequate and in general just tough on my old eyes. The Good....Quietness is what I notice most(don't ask how you notice quietness!!!), maybe just lack of anything but the signal at hand would be a better phrase. Separation between the various channels is also very pronounced. The Z-1 is very clean and very powerful. In general I do notice a distinct difference between the Z-1 and my Yamaha DSP A-1. Further listening and fiddling will reveal more I am sure. I don't feel anyone would be disappointed with this unit. Especially if you have a great pair of eyes!!
