Given an hour or so running-in, the Micromega's sound is as inspired and assured as its styling. The word 'sparkling' repeatedly springs to mind when listening to the Micromega, from the way it places vocalists in sharp focus in front of the hand to the vibrant account it gives of the acoustic of studios and concert halls alike. There's a lot of detail on offer, but despite the Duo's attentiongrabbing sound, it doesn't overwhelm music, but enhances it. It does this by placing performers in the soundstage with remarkable stability and a very real sense of space around them. Gritty rock snarls and hangs from the Micromega, while lush instrumentation of say, Pink Floyd is laid wide open yet weighty and smooth.
Highs are clean and detailed, with some glare on digital.
Mids are clear and relatively neutral, without the edge that was common to solid state of this era. Bass is authoritative, fast, and very well controlled. Strengths include dynamics and a very dark background. The chassis was finished in baked gray hammertone enamel. Telefunken produced some of the best tubes that have ever been made anywhere at anytime.
