Know before you buy
The WA6 is highly versatile and can drive a wide range of headphones, from sensitive in-ear monitors to demanding full-size models, with an impedance range of 8 to 600 Ohms.
The impedance switch allows you to optimize the amplifier's output to match your specific headphones. Using the correct setting ensures better power delivery and audio performance for both low-impedance and high-impedance models.
No, the WA6 features global voltage compatibility, meaning it can operate on power supplies ranging from 100v to 220v without the need for an external voltage converter.
The WA6 uses a self-biasing design, which simplifies maintenance by automatically adjusting the bias for compatible tubes. You will only need to replace the tubes periodically as they reach the end of their functional lifespan.
Yes, it is designed specifically as a desktop unit. It measures 6 inches high by 5.5 inches wide and 13 inches deep, and weighs 13 pounds, providing a stable and substantial footprint for your listening station.
Point-to-point wiring is a premium construction technique that avoids the use of printed circuit boards. This method is often preferred by audiophiles for its durability and the cleaner, more direct signal path it provides.
