This is a real nice sounding MC phono preamp. The AD797 has a lot to do with that. Please keep me from having to list on Fee Bay. Make me an offer.

AD797 is possibly the finest audio amplifying device devised by man. Voltage noise is stellar, and current-generated noise can be kept low using small-valued resistances in the circuit, which the AD797 will happily drive.
