DiaLogue Six

About the DiaLogue Six

The PrimaLuna DiaLogue Six is a tube monoblock power 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, with remote-controlled triode/ultralinear switching from the listening position. The amplifier includes PrimaLuna's Adaptive AutoBias circuit that monitors and adjusts bias for each power tube, reducing distortion by 40-50% compared to conventional designs and eliminating the need for tube matching. It supports multiple power tube types including 6550, KT88, KT90, 6L6GC, KT66, 7581, and EL37 with automatic bias adjustment. Construction features point-to-point wiring, proprietary wide-bandwidth low-loss output transformers with 2, 4, and 8 ohm speaker taps, ceramic tube sockets, premium Nichicon and Realcap capacitors, WBT-style speaker terminals, and gold-plated RCA input jacks. A SoftStart circuit extends component and tube life. The DiaLogue Six is a discontinued model from PrimaLuna's original DiaLogue series, succeeded by the DiaLogue Premium line.
