Overview
Dual-mono Class AB MOSFET power amplifier. Each channel is electrically and physically separate — independent transformers, independent rectifier-and-filter stages, independent output sections. Balanced XLR input only; 4 Ω and 8 Ω output taps via 5-way binding posts.
180 W RMS per channel into 8 Ω, 320 W into 4 Ω, with output impedance below 0.04 Ω (damping factor of 200 into 8 Ω). Drives the passive bookshelf speaker and most floor-standing speakers cleanly.
The canonical pairing with the desktop reference DAC as the source. AC delivery improves measurably with an audiophile power cable or a power conditioner.
