Great sound, but still only 3 stars

The first impression was okay, neither surprised nor disappointed
The build quality is fine and I have no Mängle. The only thing I would change immediately, would be the connecting cable which the right LS (in which the amplifier is) to the left. This is the first non-standard and is permanently installed in the left LS (no plug). I would like to see at least as a plug, even better would be a jack or RCA connectors.

On the right there is an LS controls for volume and regulation of ups and downs. The volume can be regulated well, the other controller is unnecessary because can not be ups and downs regulated separately. The heights If you take something out automatically Bass emphasized while these are actually well matched to the midtones.
Two single regulator would be here the more sensible choice, so one is to use in any case hardly.

Now the most important thing, the sound.
This is excellent for speakers of this size. The bass is much stronger and more voluminous than you would expect. However the high places could be a bit more precise. But all in all, there is a very good sound!
Here scores the system in any case!

Unfortunately, there are a KO - criterion which has prompted me to give this system back.
This Taste the rating 1.5 star. However, I stress this, it is a subjective experience and not to be perceived equally by all. Namely, the LS have a "significantly" passive noise audible in itself. This they have always when the power supply is turned on, it does not depend on one source and also to hear with no source.
With soft music or videos it can quiet I hear among the other noises out. Therefore, I can unfortunately only has each of a good ear and a lot of value to a pure sound places only from this system discourage. Also belated not to be as disappointed as me and the devil or any other dealer therefore makes unnecessary work by the Exchange.
Maybe I was unlucky and not any system of this series has this passive standby noise, and certainly not everyone feels this so disturbing. But for me it was unfortunately the end for the but otherwise very good Concept B20 Mk2.

Thank devil for great service!
