The Discovery is the clearest, cleanest, fastest Clearaudio I've yet heard- the most detailed, the most free-flowingly energetic, the most immediate and direct, the most alive. In this last regard, it sounds, minus the typical frequency aberrations, the way a really good single-ended triode amp sounds; as if some scrim that's been hanging between you and the music has been lifted utterly. You not only hear more; you hear more easily and rewardingly. The effect is addictive.
