The low cost attracted me, but the flexibility and sound quality justified the 5 star rating. Its loaded with useful features, and the crossover is excellent. I hooked it to a 13.8 VDC regulated linear power supply, and use it to control my woofers and subwoofer in a bi-amped tube/solid state 2.1 home audio setup. It works surprisingly well in that role. The longer I've used it, the more impressed I am. It really allows you to dial in some fine detail to your room and tastes. I was able to set and increase the crossover slopes, adjust the gain levels, setup delay to the woofers, and cut room nodes dramatically using the PEQ feature. Addressing the room nodes made a significant improvement. There's no question that this is an improvement over what just an active crossover can do....it's a bit mind boggling. I didn't find it overly intuitive to use at first, but managed to make it do what I wanted. It's making more sense as I get used to it. Great unit at this price, but I could see some benefit from having a laptop or phone control to make adjustments from the listening position....I'm guessing that feature won't be found in this price range. Definitely recommended.
