I just purchased this item today. That's why I could only give it 4 stars. I am satisfied with it so far. As many of you know, the Behringer brand is now coming up and that too with quality products. I've talked to several music people about this and most of them have the same opinion. However, there's something to be said for getting a less expensive product if you don't mind sacrificing quality. If you buy this item "BE WARNED". It specifically says in the user's manual. "When you finish using the AMP800, unplug the power supply unit from the power source. As long as the power supply unit is connected to a power source, the power supply unit consumes energy." That's probably why Behringer's products tend to "burn out" as some people have said because they leave these items plugged up when not using them. Unplug it when you are not using it. It's obviously not like most small electronics that we're used to just pushing the off switch when we're done using them. apart from that great value and excellent service from bajaao..
