Like Digifire 7.1, Fortissimo III 7.1 gives good quality output which bodes well for playback. Bandwidth compliance is more than adequate and the signal-to-noise quite good enough for a card in this range. There are a few differences compared to the Digifire 7.1, notably with regard to the THD which is lower (so better) on the Fortissimo III 7.1.
