After all this time I expected more from the successor to the Z5500 (which I've owned for years). It has more inputs, but the LCD display on the Z5500 was clearly far superior.
It's also a disappointment that the sub can't be more than 2.5M from the controller - the sub is absolutely huge and not always easy to place the requisite distance from anything electrical
There's no mention of compatibility with Dolby Prologic (which is old, true, but used by older game consoles and other devices - the Z5500 works fine with a Gamecube)
It's telling that every single review of the Z906 on Logitech's site is negative. To their credit, at least they've not taken them down..
Logitech, what were you smoking when you designed this?
