Black Ice Audio's redesigned F11 integrated amp is here! Small in stature, large in performance. This updated version of the popular JD 102BRC sees the addition of EZ-biasing and DC voltage to the filament of the vacuum tubes. With EZ biasing you turn the screw, the light goes on, the vacuum tube is biased. With DC volts the performance game is stepped up. The radical decrease in noise results in a fluid smooth clarity with a deep and wide soundstage. The elegant understated appearance works well with virtually any system and the small form factor makes the F11 a great bookshelf amp. The F11 has a big heart, delivering a surprising amount of juice even into difficult loads. Besides, the golden glow of those seven tubes will warm your heart, but not your room. Designed by famed designer Jim Fosgate.
