Know before you buy
Yes, you can switch between these modes using the remote control at any time. This allows you to instantly compare the warmer, more intimate sound of Triode mode against the punchier, more powerful Ultra-linear mode to suit your music or mood.
The Adaptive AutoBias system continuously monitors and adjusts the bias of each tube in real time. This eliminates the need for manual adjustments, protects your tubes from premature failure, and ensures the amplifier always operates at its peak performance level.
Yes, the DiaLogue Premium is designed to be bridgeable. You can pair two units together to operate them as monoblocks, which effectively doubles your power output to 82 watts per channel in Ultra-linear mode for more demanding speaker setups.
The amplifier features a built-in Bad Tube Indicator system. If a tube fails, an LED light will illuminate next to the specific tube that requires attention, taking the guesswork out of maintenance.
This amplifier is designed to work with a variety of popular tube types, including EL34, KT120, 12AX7, and 12AU7. The Adaptive AutoBias system makes tube rolling or replacement straightforward, as it automatically compensates for different tube types.
The AC Offset Killer is a specialized circuit that removes DC voltage from your AC power line. By eliminating the mechanical hum often caused by power line interference, it creates an exceptionally quiet background, allowing for greater detail and clarity in your music.
