Absolute top class - or is it?

Based on customer reviews probably choose from a lot of their products. I also! Belong If it then but should be a bad buy, the product goes back again. For Amazon, this is never a problem. Here once a thanks to Amazon for real smooth, premium and super fast service. Buy Here? Always happy !!!

Now for the product.
Of course I have this time to receive the goods quickly.
First, I should still consider that this purchase was NOT meant for me but for acquaintances.
Super packed, it took quite a few minutes, until the speakers were free.
All wiring and connection was a breeze and should not be a problem even for inexperienced technique.
The subwoofer proves here already, is the weight = sound quality.
Watt here PMPO there and then the entire music performance. Who knows what all this means and how to put the values ​​together. It says let them decide trying out and his ears.
As a connoisseur of Sennheiser and Koss, I've already tested a variety of speakers and headphones and do not say thoughtless, that my ears are very spoiled and I therefore have some expectations.

Now to the sound! Whether Klassic, rock, beat, jazz ... the sound is absolutely clean, no distort, to hear no verschrebbelten tones. The volume was not relevant to the purchase, but after the reviews I also tested shortly, how much comes out of here.
My impression: WOW ... Powerful Bass (but not tinny), balanced highs and lows. Video Movies to experience cinema-like, so I dipped into the action so far that I did not perceive the ringing of my cell phone and home phone. Although this was only a test for me, I pasted over 2 hours on the TV and sat on the couch like drugged :-)
If the small speakers are placed according to well right and left, the sound effects come over insanely great.
Further tests confirmed that this is true, the price-performance ratio. This system is worth every euro and in my opinion certainly no bad buy ... On the contrary, now I order them to me too!

One thing is still important: In order to enjoy the sound quality really, it depends on the audio source. A cheap mp3 player or incorrectly set equalizer settings nullify each sound experience. Uncompressed (original ideal purchased) Audio CDs and original DVDs are best suited. Also a cheaper player often brings with it a loss of quality.
I recommend here Orignal CDs or DVDs and compressed Musikwiedrgabe Ipod and Co.

You have to decide yourself. Give it a try ...

Addendum: The second order was blameless! Fast delivery (as always) and also here the quality was consistently good!

Addendum after 10 months:
Use the Logitech Z623 on TV and is about 2 meters. The clear sound and rich bass still impress.
BUT: The on / off switch has become a defect. Sometimes it scrapes loudly in the pit, suddenly switched off completely or sound only comes out of the right side. Flicked his index finger, it's back. Exceptional or inferior quality?
At least tasted the 1 star!
In the 2nd delivery of errors so far occurred not on. Is also rarely used. Will my review updated accordingly on.
