Know before you buy
GaNTube™ combines the efficiency and speed of Gallium Nitride power MOSFETs with the classic aesthetic and harmonic warmth of a vacuum tube. This integration allows for near-perfect switching waveforms, resulting in extremely low distortion and a more natural, transparent sound profile.
Yes, the Vivace MKII is designed to handle demanding loads with ease. With 200W of power and a substantial 48,000µF capacitor reservoir, it provides the necessary current and stability to drive almost any loudspeaker configuration effectively.
The ultra-fast 3700V/µs slew rate ensures that the amplifier can track complex musical transients with extreme precision. This results in a highly detailed, agile sound that maintains clarity even during rapid, dynamic shifts in the music.
The Vivace MKII utilizes high-quality RF-grade BNC connectors for its inputs. This choice is intentional, as it minimizes noise and ensures a superior, stable connection compared to standard consumer-grade terminals.
Absolutely. With a wide bandwidth of 5Hz to 100KHz, a 120dB dynamic range, and an exceptionally low noise floor of ≤ 45μV, it is engineered to resolve the finest details in high-resolution recordings without adding coloration.
The Vivace MKII operates with an efficiency rating of over 94%. This means it generates significantly less heat than traditional Class A or A/B amplifiers, allowing for a more compact design without sacrificing power or performance.
