I've bought the C2XD with optical input and am very satisfied. A cable for 3.5 jack and a Toslink for optical transmission (ONLY in this system) are already included! Although the included Toslink cable for the optical Übetragung has only about 80 cm., But was good enough for me. The sound for this price range is very good. You can change volume, treble and bass remote control. Likewise, you can turn on by remote control mute, which in case of unexpected interruptions (eg telephone) is helpful. The subwoofer ballert but more than I expected, and would have expected from previous reports. Turned up I get with this system very well the neighbors in the house on the mat) But for the average consumer, this system is really exactly what it needs. Especially I have no current noise or those jokes, like "older" or "favorable" devices, if you just turned up on the boxes without music time to stop. The following sentence I would like to quote from the description of the goods, as some poorer reviews here on Amazon even reported of spirits because the system suddenly changed the volume, etc .: "Patented Edifier Intelligent Distortion Control Electronic (EIDC) technology protects against distortion by dynamic management of the input signal" The amplifier thus adapts, so that as no noise during oversteer arise simply top!
I would also like to add two more citations Hinz from a test on the Internet, who then led me to my buying decision: 1. "Total Likes C2XD but by the plurality of switchable inputs, what this system enhances tremendously. The first impression is very positive, even if the X-box design probably is more likely to polarize. I enjoyed the presentation, the delivery and the first appearance very like what you would expect at about 130 Euro entrance fee also. Certainly, for the 350-Euro-row seat not quite enough to use, but you can sit at least not in the cheap parquet, back row far right. " 2. "The Edifier C2XD however, is due to the many switchable inputs the ideal choice for a smaller space in which one lives, sleeps and possibly also work or play."
Definitely recommended and worth its 5 stars for this price range and their competition! * * * * *
