My sucess rate is 95%+. You need to clearly know what you want your system to sound like. I tend to ignore any review that talks about resolution, detail, dynamics, distortion, etc. When a reviewer listens to a piece of equipment and says he played a favorite album and tears rolled down his face that is something I want to hear. Also I was a recording engineer for many years and try to reproduce the sound I got in my favorite control room. Remember all reviews are subjective as well as your own listening. You need to match them up to have any success. Your high failure rate is not knowing what you want
