The designer believes that JFETS are superior for audio amplification: “I have been advocating the advantages of FETs in general and JFETs in particular, especially for low and medium level circuits. JFETs provide extremely high resolution, bringing out more details, sounding cleaner, clearer, and more natural than the best bipolar transistors, and even the very best tubes. Overall, I believe the JFETs offer the best sound in audio circuits.”
