New global feedbackless design being an evolution of ProLogue One with novel phase-splitter and driver stage implementation. PrimaLuna Adaptive AutoBias Board with integrated plate-fuse for hassle free protection. Low-noise, high-current driverstage for higher power bandwidth, very low phase distortion and superior impulse behaviour. Superfast super low-noise rectifier circuitry. Highest quality capacitors in signal path and powersupply bypass for maximum detail retrieval and dynamic microcontrasts. PrimaLuna designed and matched wideband low-loss output transformers with optimized phase characteristics.
