Woo Audio has unveiled the anniversary version of the Woo Audio WA24 20th Anniversary Edition reference tube headphone amplifier. Each element of the WA24 20th Anniversary Edition has been carefully selected to achieve the highest sound quality. The amplifier is based on four custom-made 3A/109E vacuum triodes with medium gain and direct heating, chosen for their low noise and durability. The single-ended topology of the amplifier provides the highest gain, and the oversized output transformer - the highest power and dynamic range for even the most complex headphones.
The model operates in the frequency response from 10 to 40,000 Hz and is suitable for working with headphones with an impedance of 8 - 600 Ohms and a sensitivity of 74 - 120 dB. For connection, there are balanced outputs (4-pin XLR and 4.4 mm Pentaconn) and unbalanced - 6.3 mm and 3.5 mm.
Woo Audio WA24 20th Anniversary Edition is equipped with a precision step-up transformer STEP-UP, using a nanocrystalline core and oxygen-free copper wiring. Replacing traditional active components such as vacuum tubes or transistors, it simplifies the amplifier circuit, reduces interference and significantly improves performance. The two-tier chassis of the Woo Audio WA24 20th Anniversary Edition, made from a solid aluminum billet. Each amplifier section is housed in a separate shielded case.
The Woo Audio WA24 20th Anniversary Edition tube headphone amplifier is available at a price of $ 12,999.
