Ok Guys, as a yamaha dealer Im quoting this from my distributor. Please see the bold wording. it looks like yamaha is going the route of Sony with its ES series for some custom integrator dealer protection.
AVENTAGE is a dramatic, inspired step forward in audio/video component design.
AVENTAGE brings studio grade sound and sophisticated video enhancements to the
home as a result of unparalleled attention to detail in design, engineering, and fabrication.
Details that, at first glance, would not seem to affect the quality of sight, sound, and
control, when brought together within an AVENTAGE component, produce a work
of visual and acoustic art.
This is an exclusive Custom Integrator line of receivers which
will not be sold at "BIG BOX" locations allowing the integrator to have access to the
high levels of features and control.
