New, Vibrant, Heatsink Design
​​
Our new heatsink is inspired by the awe of the dragon. The heavy, high-density metal provides a large power reservoir and maximizes the surface area for cooling.
​
The large heatsink allows us to boost RMS power in our most popular models.
It also enables our new "Dragon" Amplifier to deliver unprecedented power levels from its all-new Class-D Full-Range circuitry.
Upgraded circuitry for model year 2025
​
​We have fully refreshed the circuitry in all models to deliver even better sound quality and faster responsiveness to transient-details.
We've also increased the number of protection circuits to make this our best performing, best sounding, most durable and rugged amplifier series to date.
Upgraded Terminals, Potentiometers
​
​We have fully upgraded the terminals and potentiometers on all models. These upgrades increase user satisfaction and increase the product feel and durability.
