Could the boxes 3 weeks now test and am very satisfied. I can not understand the sometimes devastating sound reviews! False converted MP3 files sound natural hideous, as with all models - in the Gigaworks seems to me, however - can be heard even more this quality shortcomings of MP3s, ergo: the eighth case MP3 conversion on quality! The placement of the boxes I had several times corrected (shelf in height of 2 meters, next to the screen, ...) because you have to try something, to find the optimal Beschallposition! Value for money: TOP!
