It required years of painstaking research and development and exhaustive listening trials to create the renowned DMC-30SV ‘Super Veloce’ Reference Preamplifier. The DMC-30SV succeeds the classic DMC-30SS reference preamplifier, for eight years our most popular product and one of the most highly regarded audio components in the high-end audio industry. Developed over the course of three years, the DMC-30SV is the fourth generation of the DMC-30 family which music enthusiasts worldwide have come to regard as the gold standard in state-of-the-art performance and top value. The DMC-30SV utilizes new Spectral exclusive technologies and componentry to raise the bar in signal control and amplification to a new level of precision. With the stunning success of the DMC-30SV reference preamplifier, Spectral customers have clamored for a simplified preamplifier utilizing the new SV technology. To meet this challenge, Spectral engineers have devised a new ‘straight-line’ DMC-30 which utilizes single-ended operation for inputs and outputs. This single-ended DMC-30 is called the DMC-30SC. It offers the singular performance of the benchmark DMC-30SV in a new ultra high-value preamplifier. Since the establishment of our company in the 1970s and the introduction of our very first audio component, high performance preamplifier design has occupied the highest engineering priority at Spectral. Our special focus on high-end preamplifier development over the years is based on the major design challenges which low-level amplifier and control circuitry can represent. At these critical signal levels minute amplifier distortions and signal control colorations are passed on and magnified by power amplifiers to dominate the sonic signature of the best audio systems. Spectral engineers have spent the last four decades pursuing ideal performance and signal transparency in audio preamplifiers to realize ultimate fidelity in high-end music systems.
