Woo Audio WA7 Fireflies Headphone Amplifier and DAC

Editor's Rating

Improve the quality of any audio with the Woo Audio WA7 Fireflies Headphone Amplifier and DAC. This device combines a high-performance vacuum tube headphone amp with an integrated USB Digital-to-Analog converter. With its pure tube design, Fireflies utilize 6C45 tubes in a single-ended topology. Likewise, it features transformer couple outputs. Additionally, it doesn’t use any semiconductors in its whole amplification path. Designed with 24-bit/384k sampling rate capabilities, the D/A converter provides pure data integrity. The data is transmitted through high-speed USB 2.0 interface, running in asynchronous mode. Fireflies come with an entirely aluminum chassis without visible screws and two Nickel Alloy core output transformers. Moreover, the dedicated in-ear monitors port carries an entire range of volume controls to ensure minimal noise. Fireflies also work as a standalone D-A converter, making it suitable for different system setup requirements.
