I'm using a Reference C-Core TVC to drive two Spectron Musician III SE in balanced mono-block configuration. The sound is truly astonishing. No hard edge whatsoever. The tonal balanced is very neutral. Soundstage articulation and definition is simply world-class. Bass is taught, deep with lots of detail. The midrange is quite neutral, leaning just a tad towards sounding warm. The highs are extremely clean. I rarely pass the 12 o'clock mark on the volume nob.
