Music First Audio LP 103 LCR – Universal MM/MC Phonostage

Music First Audio has introduced the new Music First Audio LP 103 LCR phonostage – a highly flexible model, ideal for working with both moving magnet (MM) and moving coil (MC) cartridges.

The heart of the Music First Audio LP 103 LCR system is a 600-ohm LCR equalizer (inductance-capacitor-resistance) section, operating with unprecedented accuracy of ±0.2 dB across the entire RIAA curve. The gain for MM is adjustable from 30 to 50 dB in 2 dB steps, and an additional gain of 14 dB, 20 dB or 26 dB is provided through MC transformers.

The input impedance for the MM input can be set from 15 kOhm to 100 kOhm, and the capacitance from 10 pF to 470 pF. The load for the MC is adjustable from 25 Ohm to 4 kOhm, so the phono preamplifier can be paired with almost any cartridge. The dual mono circuitry and fully discrete class A topology, combining low-noise J-FET input stages with a bipolar transistor system, guarantee excellent performance characteristics.

The component base is similar - Nichicon Muse KZ and ES electrolytic capacitors, as well as WIMA FKP and MKP film capacitors. In total, the design uses 6 low-noise J-FET transistors, 38 bipolar transistors, several diodes, IC and 4 LEDs.
