Preparing for this review I asked Ralph Karsten, principal at Atma-Sphere, if he planned to make a Class D preamplifier. He responded "There's not much point in a Class D preamp since you don't get the same advantages that you do in a power amp." The obvious question becomes: what are the advantages of a...
