"…Few amplifiers have had the impact or had our reference system singing to the triumphant levels that the visually unassuming MB-125s have. Call it synergy, within the microcosm of my reference system, or call it all-round potential excellence in the audio world at large. One thing’s for sure – shopping at this price point and not trying the MB-125s is totally at your peril because, in the world of the high-end, the VTL MB-125 little monos are one hell of a bargain."
