About the DiaLogue Six

The PrimaLuna DiaLogue Six is a high-quality tube monoblock amplifier featuring dual-feedback topology for superior impulse behavior and gain stability. It delivers 70 watts per channel in ultralinear mode or 40 watts in triode mode, providing enough power to drive most speakers with ease while offering the characteristic warmth associated with EL34 tubes. The amplifier includes PrimaLuna's exclusive Adaptive AutoBias circuit that monitors and automatically adjusts bias for each power tube, reducing distortion by 40-50% compared to conventional designs and eliminating the need for tube matching. The remote-controlled triode/ultralinear switching allows seamless mode changes from your listening position. Construction features hand-made point-to-point wiring, proprietary wide-bandwidth low-loss output transformers designed to handle difficult speaker loads, fully vented chassis, ceramic tube sockets, premium Nichicon and Realcap capacitors, WBT-style speaker terminals, and gold-plated input jacks. The SoftStart circuit extends component and tube life by powering up gently. The amplifier supports multiple power tube types including 6550, KT88, KT90, 6L6GC, KT66, 7581, and EL37 with automatic bias adjustment.
