Know before you buy
The hybrid design combines the harmonic richness and musicality of vacuum tubes in the input stage with the power, speed, and stability of a solid-state output. This allows you to enjoy the warmth of tubes without sacrificing the dynamic control needed to drive demanding speakers.
The Dione features an internal circuit that converts single-ended RCA signals into a balanced signal, so you can use either RCA or XLR cables without losing the benefits of its balanced topology. While you don't strictly need balanced cables, the amplifier is internally optimized to maintain signal integrity regardless of your input choice.
The standby mode keeps the internal power supplies and tube heaters at a ready state without running the full output stage. This significantly extends the lifespan of the tubes by reducing thermal stress while ensuring the amplifier reaches optimal performance quickly when you are ready to listen.
Yes, the Dione is engineered for stability and precision, delivering 180W into 8 ohms and increasing to 280W into 4 ohms. Its overbuilt power supply and robust design allow it to maintain control over a wide range of speaker loads, even those that dip into lower impedances.
The Dione uses one 6DJ8/6922 tube per channel, which are pre-burned and matched at the factory for accuracy. While these tubes will eventually need replacement, the amplifier's design is optimized for longevity, and the standby mode helps preserve their life during periods of inactivity.
The optional high-pass crossover is useful if you are integrating a subwoofer or using a satellite speaker system that requires filtering out low frequencies from the main speakers. If you are using a standard full-range speaker setup, it is not required.
