Know before you buy
With 8 watts of power per channel, this amplifier is best suited for high-sensitivity speakers. It will perform exceptionally well with horn-loaded designs or full-range drivers that can translate the nuance of the 300B tube into a room-filling sound.
Yes, by isolating the power supply and signal paths for each channel within one chassis, the amplifier minimizes crosstalk and interference. This design provides the sonic separation and imaging typically associated with separate monoblock amplifiers while saving significant rack space.
Zero-feedback circuits prioritize natural harmonic structure and transient speed over the clinical precision of measured distortion. This results in a more organic, lifelike presentation that excels at reproducing the texture and decay of acoustic instruments.
As a tube-based amplifier, you will eventually need to replace the 300B power tubes and the 5751 input tubes as they age. Because this is a hand-assembled, high-quality unit, it is designed for longevity, but you should ensure the unit has adequate ventilation to protect the internal components.
At 102 pounds, this amplifier is significantly heavier than most consumer-grade gear. You should verify that your audio rack or shelf is rated to support this weight and that the surface is stable enough to handle the concentrated load.
The Gen 6 power supply is engineered to lower the noise floor, which is critical for SET amplifiers. By reducing ambient hum and electrical noise, it allows the amplifier to reveal finer low-level details and micro-dynamics that might otherwise be masked.
