Fiio built its name on pocket DACs and budget desktop amps, then started aiming at real stereo hi-fi. The EA13 is its first full vacuum tube amplifier: Class A, two channels, six tubes — a pair of Sylvania NOS PCF80s handling voltage amplification into four JJ Electronic EL34s. It drives passive bookshelf or floorstanding speakers, glows the way the category demands, and lands well under $1,000.
