Liquid Fire Features
The Cavalli Liquid Fire is a hybrid headphone amp, meaning that it uses a combination of tube and solid-state-powered output circuitry. While hybrid circuits, per se, are not new, there are several aspects of the Cavalli design that are quite unusual and distinctive.
Cavalli strives to provide a best-of-two-world’s design, combining the transparency, harmonic richness, and sonic liquidity of great tube circuits with the cleanliness, precision, and control of great solid state circuits; hence the name Liquid Fire.
The Liquid Fire has two output jacks. One jack is wired directly to the output stage for high Z headphones. The second jack is provisioned with 50ohm resistors in series with each channel’s output to, effectively, reduce the gain for low Z headphones.
