How does the Rock 7 sound? For large-scale orchestral music, it redefined what I thought an orchestra could sound like on my stereo system, and on other types of music, it brought me closer to the performers than I had ever experienced prior. Moreover, this feeling of discovery persisted every time I put on a different record. Each experience was a new one. The Rock 7 had the most profound impact on the sound of reproduced music in my home than did any other equipment change I had ever made, including changing speakers!
