Very good system equipped with low-quality speakers

First, I want to mention that I have about 4 months, the system had initially awarded to another portal 4 stars. But would like to give some hints for future buyers.
The Samsung 7.1 system I bought in the first place, to have a coordinated device to Samsung TV via the HDMI interface. Both work very well. Player, Software and menu guidance correspond to what I had wished for. Also the separate receiver unit for the rear speakers is solved for me perfectly, so as not to allow additional cable run through the living room. Visually, the player / amplifier acts also very elegant, which I at first believed by the aluminum design of the boxes. Unfortunately, the boxes are completely visible with me, and then you can see the built black plastic on the other side of the high-quality-looking aluminum design front. The whole thing has me then sometime annoyed, see, eg, also the Center Box "Klotz", so that the boxes now fully available for sale with me. But that's not the only reason the pit exchanges. The passive bass box has absolutely no sense of bass, the product can be found, incidentally, in other Samsung plant here now I am running an active box. The center box is the way it looks dimensioned too small. The rest goes.
Samsung would have with this system. Already a fairly high-quality product on offer when the loudspeaker components would be suitable to With my replacement components I have now my desire conditioning. For this was but said that the Samsung speaker cable must be re-used, due to the specific interface.
Conclusion: If a matching 7.1. Annex to the Samsung TV wants is right with this system. Who wants the hoped cinema sound, you will be disappointed here and have to refuel.
