Thirteen years later, building on everything they had learned about capturing the purest sound, Guttenberg returned to produce The Ultimate Demonstration Disc Volume 2. Designed to bridge the gap between technical terminology and the listening experience, this collection serves as a practical guide to the audiophile lexicon. On each track, Guttenberg "spells out" exactly what to listen for, providing clear musical examples of concepts like "transparency" and "soundstage depth." By using a custombuilt recording chain and avoiding dynamic range compressors, equalizers, or overdubbing, the album captures a "live" session exactly as the microphones heard it - resulting in a sound so neutral and natural that it can be used to reveal the subtle differences between high-end speakers, electronics, and cables.
