Al, he states that almost all (he doesn't say which were not) measurements were taken from the RCA jacks, which would be the preamp outputs. As the outputs are wired in parallel, the output impedance should be 2 ohms, as are the headphone and speaker outputs.
I've seen many irresponsible things done in with connections my time at LTA but I've never seen an MZ2 damaged from what's going on at the output.
