(A Letter from Dan D’Agostino continued)

I have some exciting news for you. Work on a new source component for the Evolution Series is ongoing as of this writing. Possessed of the unique Evolution technologies that power the amplifier and preamplifier, this Evolution source will expose the real advantages of the latest recording formats while taking compact disc playback to the next level. I encourage you to audition it as soon as it is released.

Sincerely,

Daniel D’Agostino
