I feel that this system is an excellent basic system especially for a small room. It can be added to sourcewise with the addition of a preamplifier and tuner, SACD, and vinyl sources. One could subsitute a fine low power tube amp for the Aleph if one prefers this sort of sound. A balanced amp, like an Aleph 5, might provide some sonic advantages with the Wadia which sounds best with balanced cables, IMHO.
