FiiO EA13 Stereo Valve Amplifier — Black

The FiiO EA13 is a black stereo valve amplifier built around Class A push-pull amplification. Its preamp section uses two PCF80 valves, with four EL34 valves in the power stage. Four selectable RCA line inputs allow connection of analogue source components; a turntable requiring phono equalisation needs a separate suitable phono stage. Dedicated speaker connections provide 4-ohm and 8-ohm options, while a 6.35 mm single-ended headphone socket supports personal listening. FiiO specifies at least 18 W per channel into either 4 or 8 ohms at THD+N below 1%; its higher 28 W per-channel rating uses the less stringent below-5% condition and should not be treated as the same measurement. Mechanical VU meters and rotary controls provide input selection and volume adjustment. The chassis measures approximately 430 by 339 by 145 mm and weighs about 17.7 kg. A 3.5 mm trigger input supports system integration. This model has analogue line inputs rather than a built-in Bluetooth receiver or digital DAC; speakers and source equipment are not included.
