The WA7 Fireflies (2nd gen) is a desktop headphone amplifier with an integrated asynchronous USB DAC. Its amplifier is an all-tube, single-ended Class-A design with transformer-coupled outputs, using two 6C45 driver/power tubes. The DAC uses an ESS SABRE ES9018K2M and supports high-resolution PCM playback up to 32-bit/384 kHz. It has a 6.3 mm headphone output, a 3.5 mm output intended for sensitive in-ear monitors, and an RCA analog input that can also serve as an output in DAC mode. The standard configuration includes an external solid-state linear power supply; the WA7tp tube power supply is an optional upgrade, not part of the standard model.
