This moving coil amplifier is my attempt to create a silent and "neutral" MC Head Amp. IC circuitry, non inverting config, using AD 797. Not the newest, but it's noise figures are still hard to beat. Other parameters; distortion, slew rate etc. are fine. AND you can still get it in a DIP package and put it in a socket connector, easy replacement/upgrade. Standand circuit solution, just be careful with decoupling and ground paths.
