    Foreword: The Big Dipper is LZ's flagship, sporting 7BA drivers and a triple-switch mechanism that modifies bass, midrange and treble. This unit was loaned to me by @Brooko but unfortunately had some driver damage right after I finished measuring. So, no subjective impressions, just graphs.

    Graphs below are performed with all switches up (lowest total impedance).
