Dan D’Agostino Momentum C4 Preamplifier: High End Munich 2024

In normal operation, component heating can lead to performance and sonic degradation. Developed specifically for the Momentum C4 Preamplifier, a unique circuit maintains a stable bias so that temperature related anomalies are offset thus preserving performance during extended listening.
Utilizing no negative feedback anywhere, core D’Agostino circuit concepts include a signal path that is fully complementary, direct coupled, and balanced from input to output achieving a frequency response flat to 120 kHz.
All signal gain is realized in the current domain using proprietary multiple-output current mirrors with nearly 30 times the linearity of other designs. Executed with four-layer circuit boards for superior signal quality, the use of four-layer boards dramatically reduces distortion and propagation losses as compared to the more commonplace, two-layer boards.
