I just purchased a pair of Super Zero 2.1 to connect to the Griffin Twenty amp and play my pc music. This replaced my Cambridge Soundworks 2.1 speakers and the difference is night and day. The richness of the 2.1's blow me away. I hear things I hadn't before and the amount of bass is perfect for me. I was constantly adjusting the Cambridge due to the bass and now the only thing I mess with is the volume. I own only NHT speakers (Absolute Towers and b10 sub, also the discontinued NHT Verve speakers for TV audio) Great company and great people. Looking for future releases from NHT!
