Unfortunately, the device arrived damaged, according Urgenz the return paperwork was answered immediately and the documents were sent quickly. ELECTRONIC STAR was at pains to relieve customer friendly and responded quickly, but I have the impression that the receiver does not fulfill even for this price also slimmed expectations. Although this device looks wertig, but apparently you can not rely on the built-in technology. Electronics Star has a number of good amplifiers well-known companies in the program, just the heart of a surround sound system can 100 Euro more miracles wirken.Fazit: this unit is not recommended. Unlike the ordered Hyundai-standing speakers: buy 4 pieces, fired with a Pioneer amplifier they deliver fantastic surround sound, just perfect!
