A Current-Domain Electrostatic Amplifier for Stax Omega II Headphones

A Current-Domain Electrostatic Amplifier for Stax Omega II Headphones

The amplifier operates primarily in the current domain. The first stage is a voltage controlled current sink. The second stage is a current-controlled voltage source.
The fourth stage is a constant current sink. The main advantage of current domain amplifiers is speed. Standard voltage gain amplifiers with lots of gain are affected by the Miller Effect which prohibits extended frequency response.

This solid state amp is so much better than my tube amp that I no longer listen to it. I’m not a solid state snob; it’s just plain better. The people who have listened to this amplifier (some of whom were giants in the industry in their day) love it, much more than my tube amp. I love it too. I can’t stop listening to it. The tube amp has moved into a secondary position in my listening rack.
