I heard the Magico S3 MkIII yesterday on the Dutch Audio Event show, and they sounded absolutely marvelous. Boy, did the S3 MkIII's sound ever so fantastic! I was deeply impressed. Clearly, in every way, it is a massive improvement over the S3 MkII, almost incomparably so. The treble is ultra-refined, airy, and delicate yet not soft. The midrange is pure, clean, and detailed, yet majestic and smooth, with just the right dose of tonal saturation, and the bass is powerful, deep, and articulate. The overall sound of the S3 comes across to me as cleaner and purer, airier, more delicate, and more refined than the previous S3 MkII. Whereas I found the S3 MkII's midrange to have a subtle coloration, this is nowhere to be heard with the new S3 MkII. I am pretty sure this is thanks to the plastic cone being removed from behind the midrange unit. The last point really is more of an educated approximation than a proper assessment, but I have a feeling that the imaging and soundstaging are also improved. Compared to the S1 MkII (that I still own), I found the S3 MkII to sound spatially constrained, almost flat. Together with the midrange coloration, this was why I decided to stick with the S1's at the time. However, based on what I heard at yesterday's show, the new S3 produces a beautifully large and deep soundstage bubble, and the sound breathes entirely freely from the cabinets.
