KRELL DESIGNER DAVE GOODMAN ON IBIAS AND OTHER FEATURES

he K-300i uses modern techniques that we’ve implemented in the recent designs and upgrades we’ve issued since the split. First, it has a differential current-mode input stage that drives a fairly conventional output stage. Though we’ve done such designs before, I discovered that by fine-tuning parts of the gain stage I could significantly reduce distortion—specifically the second-harmonic component. The predominant characteristic is now the third harmonic, which we’ve found
