Other reviewers have criticized the weak basses of Avenza. That reminds me, this was not too important, I still decided to buy. Disappointed does the Speedlink system at the end of a completely different reason: the grottigen heights. Here you get constant oversteer, a crackling and creaking even at low volume. Warm ups such as. Of a piano, synthesized sounds about by post-rock ambience or even lighter voices in movies and audio books are distorted beyond the pale.
To clarify: I expected no hi, but only the reproduction eg an ordinary MP3 file (320 kps, 44 kHz), without that I would tease me about the sound quality. But even a 17.99-No Name-product from the electrical discounter has since given me more pleasure than the Avenza.
After other users marked shortcomings, I assume, in this state is not a production error, but a general weakness of the system.
Pluses I can only for externally excellent workmanship, the tasteful design and the power saving function to give (although standard nowadays!), Which shuts down the entire system after a few minutes with no sound reproduction and activated when required by itself again.
Conclusion: Not recommended. 2/5
