Know before you buy
The Gen 2 Inverted Triode technology is designed to provide a unique hybrid sound profile that combines the harmonic richness of vacuum tubes with the speed, control, and dynamic authority typically associated with solid-state designs.
Unlike traditional potentiometers or resistor ladders that can degrade signal integrity, the multi-tap transformer attenuation adjusts volume by changing the transformer ratio. This preserves the signal's purity and maintains consistent impedance across all volume levels.
Due to its extreme mass and the presence of 10 independent power supplies, you must ensure your audio rack or stand is structurally rated to handle the weight. It is also recommended to place the unit on a stable, vibration-isolated surface to allow the internal components to perform optimally.
Yes, the unit features both RCA and true balanced inputs. It also offers on-demand XLR outputs, allowing it to integrate seamlessly into a wide variety of high-end audio chains.
The quad choke filtered power supply is engineered to provide an exceptionally clean and stable voltage to the sensitive audio circuits. By effectively filtering out electrical noise, it allows the preamplifier to deliver a lower noise floor and improved transient response.
The high gain version provides up to 14db of gain and a 10Vrms maximum output, which is ideal for driving amplifiers that require a higher input voltage. However, if you are using a very high-sensitivity power amplifier, you should ensure your system gain structure remains balanced to avoid excessive noise.
