  • The Long Story

    Meet Tube-Tech

    The WA7 Fireflies uses 6C45 tubes in a class-A, single-ended topology. So that you get only pure sound, there are no semiconductors used in the entire amplification path.

    Amp it Up

    Inspite of its tiny size, this device is able to drive just about any headphone & earphone. It has a special IEM port as well as a variety of volume controls. The WA7 Fireflies can also be used as a standalone DAC. It uses an ESS SABRE DAC that is able to convert up to 24-bit/384k sampling rates.

    Feel the Power

    A standard high-speed USB 2.0 interface maintains the audio signal quality during transmission. Along with this, there is also a custom built toroidal power transformer, remote-controlled linear external power supply for amplification circuitries and multi-layer military grade PCBs.

    Durability with Style

    The WA7 Fireflies (2nd gen) Headphone Amplifier / DAC will look great in your home and is built to last. The entire chassis is made out of anodised aluminium while the output transformers have a nickel-alloy core. To further enhance the WA7 Fireflies' looks, Woo Audio has made sure that no screws can be seen.
