NAD Viso 1Price: $600

Colin said: The NAD Viso 1 is an astonishing sound machine, and an epic achievement for its product category: It offers a purity of sound that no reasonable person could have expected from an iPod dock. Its digital innards, born in a $6000 technical marvel, perform amazingly well in this $600 version, and, mated to PSB’s overachieving drivers, offer tight, almost unreasonably deep bass, sparkling but never overblown highs, and a clarity that must be heard to be appreciated.
