​​​​​​​Aurora One Tube Line Preamplifier & Buffer


The Aurora One tube line preamplifier & buffer acts as a bridge between your analog sources and power amplifier. Featuring a Class-A non-feedback open loop all tube signal path, the Aurora One offers complete transparency with extraordinary low distortion and noise. With 6 analog inputs, this line preamp has enough overhead for even the largest systems.


This preamp also offers 3 modes of operation; Low Gain, High Gain, and Bypass. These modes can be pre-programmed by the user for each of the 6 inputs. When a specific input is selected, the preamp will automatically recall the user-programmed mode and displays the status via the LEDs on the front panel. This unique feature allows for better volume matching between inputs with different signal strengths. Not only does the user not have to continuously tweak the volume, you no longer have to worry about going deaf by accidentally switching to the wrong input!
