The CORTESE LCR preamp is identical to the Cortese but uses a LCR (Inductance,Capacitive,Resisitive) network in the phono stages RIAA equalistaion network.
The expensive custom built Lundahl inductors used in the LCR preamp give a very worthwhile improvement in the phono stages vividness and sense of midrange realism. LCR networks are used in some of the worlds most expensive phono preamplifiers, but the CORTESE LCR is the only moving coil capable LCR phono preamp.
The Cortese LCR is designed for use with high quality low output moving cartridges with a range of 0.1mV to 0.3mV .
Incredible sound, incredible value.
