Wojciech Pacula has posted a review of the RT Audio Design Orpheus MkII (~€750) at High Fidelity. His conclusions:
“This amplifier offers simply beautiful sound. But its bass doesn’t go very deep, is not particularly well controlled and it is rather warm. But it’s tonality, and spacing is wonderful – it creates an impression of a bubble, without clearly defined contour, that listener sits in. Micro-dynamics is remarkable, macro is definitely not that good.”
