This comprehensive deep dive explores the design philosophy, engineering marvels, and sonic performance that make these power amplifiers highly sought after by audiophiles and collectors today. The Heritage of Musical Fidelity
To keep the noise floor as close to absolute silence as possible, the FX power amplifier utilizes fully balanced XLR inputs alongside traditional unbalanced RCA connections. Balanced circuitry naturally cancels out electromagnetic interference (EMI) and radio frequency interference (RFI) picked up over long cable runs, ensuring that only pure music reaches your speakers. 4.
