Selling my Firestone Audio Fubar IV Plus DAC and headphone amp combo. Also acts as a DAC/preamp. Connects through optical, COAX or USB. Can do 24/96 through the optical connection. It's a very nice sounding unit and has served me very well. Upgraded to AD797 op amps (well pretty sure it's AD797 LOL). Retailed for about $400.
