 **Contribution:** Concept origination, development, and implementation.
-**Discussion:** This was a continuation of the work I started with the Transcendence Five. Historically, AVA had demonstrated some success with two different hybrid approaches. In the first, high-voltage MOSFET buffers were placed inside the main feedback loop of vacuum tube gain stages. In the second, a low-cost opamp stage was used to provide high impedance buffering of a conventional closed-loop tube preamp design. My idea centered around placing a high-speed solid-state buffer IC stage //inside// the global feedback loop. This would allow AVA to offer a preamp with performance that exceeded their tube/MOSFET hybrid at a considerable cost savings. This design was so good that it obsoleted their tube/MOSFET hybrid preamp until I was able to complete work on the Transcendence Seven.
