I bought it based on one review on Thomann, beeing disapointed by my hi-end system. I am sixty plus, I love Dream Theatre with their spotless recordings, but my emotions are in seventies. Myself play drums and love sound bass. I always lacked the low spectrum on that classic recordings in my system. What this small and expensive box is providing is EXACTLY what I have been missing. I can play with bass and drums sound, put a firm fundament, pick up snare or kick. I am totally delighted. The same is possible in middle and high range, but in this field my system works awesome so no need to intervene. In recent world, when all hi-end producers are offering just linear systems, I am happy to find a way. Owesome product.
