WOO Audio Fireflies 3 - Balanced Headphone Amp / Preamp / DAC - SILVER

Woo Audio WA7 Fireflies 3rd Generation, an all-in-one tube balanced headphone amplifier, DAC, and analogue preamplifier. This latest generation features upgraded internals, improved power regulation, and delivers Woo Audio’s signature warm, transparent, and highly musical sound. Built around dual vacuum tubes and a Class-A analog output stage, it's a minimalist yet powerful solution for desktop or home listening. It includes a USB input only, feeding a high-quality ESS Sabre DAC that supports PCM up to 24-bit/384kHz and DSD128. Outputs include both balanced 4.4mm and unbalanced 1/4" headphone jacks, easily driving everything from sensitive IEMs to power-hungry planars. The WA7 also functions as an analogue preamplifier, letting you feed powered speakers or a power amp directly through its variable line-level output. The unit is in excellent condition, comes complete with original packaging, stock tubes, external power supply, USB cable, and manual. Tubes have less than 100 hours of use.
