Phono Preamps & Signal Chain

A phono cartridge produces a signal roughly one hundred times quieter than a standard line-level source, and it needs both amplification and RIAA equalisation before reaching an amplifier. This category covers phono preamplifiers ranging from entry-level built-in stages to discrete Class-A designs with adjustable gain and MM/MC switching, plus the supporting components that complete a transparent signal chain: step-up transformers for very low-output moving-coil cartridges, linear power supplies for the quietest possible noise floor, and subsonic filter modules that protect woofers from the low-frequency energy produced by warped records.
