It is a little early to say. Upon initial listen, the Calypso is very good, as I expected it to be. I like the bass better than on my (previous) decked out Atma-Sphere MP-3, and the whole presentation is clear and dimensional, but it is a different sound compared to the organic and vibrant sounding MP-3. Comparision to the Vibe is more difficult. They are both excellent, and each seems to have its own strengths. I cannot yet say which I will keep, and I do not believe I yet have the full measure of the Calypso, so maybe I will be able to comment more specifically after I listen some more.
