The 5.1 surround system Logitech Z-5500, clearly proves that Logitech may have a say in the world of sound and has something to offer and have not only the company as hell and Co. or whatever are the only ones that are supposed to offer something , I made this sound system are already for 7 years in my apartment (now it is getting old ^^) and it still works flawlessly and delivers great sound. The sound signal comes from the good old Audigy 2ZS of Creative. I have a surround sound system sometimes long directly operated for a short time with my 7.1 sound-enabled motherboard onboard. The difference was only too clear to hear all and I'm instantly jump back on a sound card. Whoever buys the Z-5500, but should also have a certain room size bring (> = 20m²)! The speakers are all on separate control instance freely adjustable. Using a software (for example, comes with the sound card) but you can tease out a really good maximum and calibrate each speaker so that the perfect sound is aimed at a certain point in space. The subwoofer is, as befits a wooden box in which the amplifier is installed together with associated electronics and forms the central authority to which all the cables are connected. It provides a very "smooven" Bass and brings everything (if you want) to wobble. Why did I but still only awarded 4 stars, although me this surround system has so convinced. The reason is the sensitivity of the amplifier to the applied power supply. He seems to be bad abgschirmt to fluctuations in the power supply. Even though the power supply is screened very old and bad, you can hear the power on / off other equipment to the mains, a popping out of the amplifier. This may for example even happen when you turn the lights on or off. In addition, a slight Brummgeräsch comes with the power supply that particular standby mode if all is quiet in the room, can be heard clearly. Although I disconnect the power supply anyway, if I do not use it, which still is not acceptable! I do not know if has now improved the Z-5500 over the years hinsichtlicher these shortcomings somewhat, but despite all the merits of this surround system its 4 stars, since, in contrast to many other would-5.1 systems an excellent Sound offers, which compensates in some way for these shortcomings. The Z-5500 due to the high power consumption also eats a lot of power! Angsichts of high electricity bills, which is fluttered into my house, because I had the Z-5500 is almost always turned to listen to music, I have a little brother brought me (the X230) from Logitech, which also has for its 2.1 sound an excellent sound returns. I run the Z-5500 only when I want to sit back times and the times would sound really enjoy. This is often enough, for example if I bought a new music CD: O)
