We have several customers that use our M-60s on Maggies, 1.6s and 1.7s.
Since the M-60 is a small OTL, it does not handle 4 ohms well so they use a set of ZEROs and seem quite happy with the results (about 80 watts with this setup). Other than the impedance, the speaker is easy to drive, that is to say it has a moderate efficiency and almost no phase angle at all.
Traditionally in this neck of the woods, Maggies and tubes have been used together quite often- Audio Research is on the other side of town so the two have been used together for decades.
