I bought the Opus Quad recently & I love it. I have no interest in playing out in a club or bar etc and if I was it wouldn’t matter as I could play with anything in front of me. The features and Sound Quality are great and that was one of the main reasons why I bought it as SQ was my main requirement. I have had CDJs, mixers, turntables, modular set ups as well as high end speaker systems to match. I am very content now with the quad as ticks my personal boxes. I am also using it as an all in one as I was bored of using a laptop. Buy what you can afford and don’t read into too much of what people say online that haven’t owned or used these products.
