For this device I can easily attest only my real satisfaction.
The sound is really very natural and if necessary, a warning reason in an apartment building.
All relevant connection options are available from home and the included cable.
I run the system visually a Creative X-Fi. After the business phase really a compelling backdrop.
The separation of the Z5500 I do not regret in the least, though of course has to be said that the focus
with me is on music and not on gaming or video. Otherwise, I would have certainly gained the S550.
Those who absolutely brutal needs, which must probably determine the S730D or something equal of a competitor,
but for very melodious sound of a 20m²-room enough this system of loosely.
