Yes, impedance matching is always an issue with tube preamps. In addition to that there is the issue of the preamp being normally unbalanced in internal operation so that using balanced connections introduces crossover distortion in converting from SE to BAL and back. The Magtech solution of treating both inputs seriously with an eye to optimizing the most likely preamp options to go with each is very welcome.

Not surprised by the Magtech running hot. Running that much current for the 3.7i and the pair of DWM requires much power and is a rather low impedance load so is a very high current requirement. While the maggie spec is 86 db sensitivity, independent measurements in the full spectrum are more like 83 db sensitivity.
