FireS Audio Fubar HD
Versatile Dac/Amp Combo
Combining a DAC and solid-state amplifier in a compact form factor, the FireS Audio Fubar HD is capable of driving everything from the most delicate IEMs to power-hungry, 250-ohm beasts. It supports 24-bit/192-kHz playback through the coaxial input and 24-bit/96 through the the USB input. With multiple input options, versatile output functionality, and the option for an upgraded separate power supply, the Fubar HD is a great system to start with and upgrade as your needs change and your budget increases.
Easy to Upgrade, Easy to Love
Exemplary of the company's (formerly called Firestone) exceptional acoustic tuning, the Fubar HD is well balanced in the highs and lows, and shows no audible hiss—even on the high-gain setting at maximum volume, listening through sensitive IEMs. Plus, because this DAC/amp uses swappable solid-state opamps for signal amplification, it’s easy to upgrade and tweak. Much like vacuum tubes, different opamps produce different sound signatures and different levels of clarity. Swapping is as simple as unscrewing the case, pulling one out, and tossing another one in.
