About the SFP-1
The Sonic Frontiers SFP-1 is a high-quality phono preamplifier designed for both Moving Magnet (MM) and Moving Coil (MC) cartridges. It uses Sovtek/Mullard 6922 and 12AT7A tubes in its circuitry. The SFP-1 provides 37 dB of gain for MM cartridges and 57 dB for MC cartridges, with a total harmonic distortion of 0.05% at 1.0V input. It features a channel separation of over 40 dB and an output impedance of 1 kΩ at 1 kHz. The unit is well-regarded for its sound quality, offering a deep soundstage and a weighty midbass, though it may lack in bass extension compared to some solid-state alternatives.
