The Z4 system I have now (estimated) 3-year on PC and am actually more than satisfied. Have just out of curiosity here the tests read and was amazed that such a negative review of the system comes partially materialize. I admit I have very little idea about sound systems (brightness and depth Height adjustment tell me nothing and I've never dealt with the Sound settings - just trying currently to find out how things are going because I want to switch to a surround system), but as Standard users with reasonably functioning auditory ;-), I'm really happy with the sound. It may be mentioned that I previously had a NoName speaker system that has really been good for zero and thus leads to the ego a little more enthusiasm for my system show as attached, but oh well ... Personal conclusion: Sound is good. Appearance also. Connection was not a problem (as far as I have in mind). Negatives: When switching over the operation make the speakers sound as if you want to give up the ghost, but everything still works.
