Woo Audio WA5

The WA5 features discrete amplification sections for both speakers and headphones, but it is designed to output to only one source at a time. You can easily toggle between your speakers and headphones using the front-panel output selector.

The WA5 includes user-selectable impedance settings (HI/LO) to ensure optimal synergy with your specific headphone model. Generally, use the LO setting for low-impedance headphones and the HI setting for high-impedance models, though you should experiment with both to see which provides the best dynamic range and control for your specific gear.

Yes, the WA5 consists of two separate units—the amplifier and the power supply—each measuring 12" x 9" x 17". You will need a sturdy rack or shelf space that can accommodate both units side-by-side or stacked, keeping in mind that you must allow for adequate ventilation for the tubes.

Yes, the WA5 features global voltage compatibility, allowing it to operate on power grids ranging from 100v to 240v. This makes it a versatile choice for international audiophiles without the need for external voltage converters.

As a Class A single-ended triode amplifier, the WA5 relies on vacuum tubes that will eventually require replacement based on usage hours. The unit features autopolarization for compatible tubes, which simplifies the process, but you should be comfortable with the occasional need to source and swap matched sets of 6SN7, 300B, and 5U4G tubes.

Yes, the WA5 is equipped with one XLR input for balanced sources and two RCA inputs for unbalanced connections. This allows you to connect multiple components simultaneously and switch between them as needed.
