Just came across a July 2012 review of the D.D. Momentum monoblocks by "Audio Esoterica" which is a new Australian audio publication and whose editor is Edgar Kramer.
According to Edgar Kramer, "Audio Esoterica" is purely based on high-end equipment, and is a separate publication to "Australian Hi-Fi" magazine, even though it came as a lift-out section originally published in "Australian Hi-Fi" Magazine (Jul/Aug 2012).
