"If the bias supply is reduced to 280V, the amplifier will drive all electrostatic headphones. I tried it last night on a pair of SRX's. I never ever heard them sound so good."

a bit more......

"Biasing the headphone diaphragms: The diaphragm bias network for the AC-coupled amp is shown in figure 5. The AC-coupled amps will work with any electrostatic headphone, if the bias voltage is correctly set. Older Stax units are low-voltage bias (~330V). Most of the newer Stax are high-bias (560V)."
Who's going to tell him??
Typo not only once.

If your bias is too high, there is an increase in sensitivity and an increased risk of damage to the drivers. So i have to recommend staying close to the designed bias voltages. |
