About the REF501S
The Bel Canto Design e.One REF501S Stereo Amplifier is a compact, all-aluminum chassis unit providing powerful 250W per channel output (1% THD) with high current capability (17.5A peak), designed for dynamic, high-resolution audio performance. It features a DC-coupled signal path without capacitors, an impedance-optimized input stage with high common-mode rejection, and an innovative 5th-order loop filter for ultra-low noise and distortion across the audio bandwidth. Using Hypex NCore Class D technology, it offers precise control, wide dynamic range, and compatibility with loads down to 2 ohms. Inputs include single-ended RCA (47kΩ) and balanced XLR (95kΩ), with dual sets of WBT Nextgen 5-way binding posts for outputs. Engineered in Minneapolis, Minnesota, it runs cool, preserves musical detail, tone, and dynamics, making it ideal for high-end systems paired with preamps like the Pre5.[1][7][9]
