Description
Woo Audio WA5 Gen 2 Headphone and Integrated Amplifier
The WA5 sets the standard for 300B based amplifiers and features separate speaker and headphone amplifiers in two discrete amplification sections to achieve the highest performance in both forms of usage. The power supply is divided into different units to ensure that the audio signal is pristine and isolated, and advanced output switching enables the user to select speaker or headphone output effortlessly. It is the most versatile amplifier for high-efficiency speakers and any dynamic/planar headphones.
Unique to WA5 is the user-customizable headphone output (HI/LO power, HI/LO impedance, and HI/LO level) located on the front panel. When used in conjunction, the user can optimize the synergy between amplifier and headphones to achieve the ideal pairing and performance. At maximum, headphone outputs get full eight watts per channel – easy to satisfy the needs of any demanding headphones.
To tailor different user requirements, we also offer a headphone-only model – WA5-LE – which boosts the same headphone circuitry and functions as the WA5.
