Speaker evaluate the point I find very difficult because everyone perceives another sound and there are also strong differences in taste like the sound should sound. Then speaker is not the same speaker, because a decision on the Sound is still the weakest link in the chain. With music on the PC, this would be: quality FLAC file, sound card, length and quality of the cable, amplifiers, speakers. If an inferior FLAC file is played or even mp3 files or the soundcard already in GDR times for a renewal screaming then the subjective (bad) sound perception is not attributable to the boxes. Only when in the chain up to the boxes a high standard of quality is guaranteed, the speaker can produce an even "better" sound. I myself can use my PC despite Flac not approach the sound quality when I listen to music via CD, or on my system CD + amplifier. My sound card is simply too weak for these boxes. If I consume my music on CD, I can only say that boxing knock one, just on higher volumes simply. In normal speech could still resonate a bit more bass, but otherwise also an excellent sound. It has at times feel it is in the middle of a live concert, the votes go to the marrow;) There are probably even better speakers, but certainly only on the 400 limit. Just as I graduate just did not not even just to avail the funds as much money in the hand. I also play for min. 60% from my music on the PC, and as mentioned above would then only a new PC forth as more expensive boxes. I can put these boxes all only to the heart, I have rarely heard better! The processing is also incredibly high. For the price can really be reached without! Greetings
