XF-2 Type L

About the XF-2 Type L

The Fidelity Research XF-2 Type L is a moving-coil step-up transformer specifically optimized for very low-impedance, low-output MC cartridges in the 0-5 ohm range, such as various Ortofon SPU and Fidelity Research low-impedance designs. It provides high gain of approximately 36 dB in the Type L configuration and is intended to feed a standard 47-50 kohm MM phono input, making it suitable for use ahead of dedicated MC stages or MM-only phono preamps. Like the better-known XF-1 Type L, the XF-2 Type L offers a wide playback frequency range around 5 Hz-50 kHz, allowing very extended bass and treble response with minimal phase shift and coloration. The XF-2 line is documented as having different versions (L and H) to cover distinct cartridge impedance ranges, with Type L matched to 0-5 ohm cartridges and Type H to higher impedances, reinforcing its role as the low-impedance specialist in the series. The XF-2 Type L shares the compact but hefty form factor typical of Fidelity Research MC transformers, with an approximate weight around 2.1 kg and a dense metal enclosure that helps control vibration and shield the transformer from hum and electromagnetic interference. Within Fidelity Research's SUT range, the XF-2 Type L sits alongside the XF-1 L/M/H models, complementing them by offering alternate core and winding implementations and alternative impedance/gain options. The XF-2 Type L is regarded as a rare, high-performance vintage component with clean, neutral transfer and substantial gain for very low-impedance MC cartridges, and remains sought after on the used market by enthusiasts looking to pair classic low-output cartridges with modern or vintage MM phono stages.
