Wayne Donnelly, in his review of Spectron Musician III (standard) made some comparison with Parasound Halo. Today, Musician III Signature Edition is way, way better then standard Musician III and if you want "iron fist" amplifier' control over the speakers AND live music representation of the best tube amplifier - you cannot find better amp then Musician III SE.
BAT600SE is also excellent amp but twice more expensive then Spectron
Good Luck
