This component amplifies the weak signal generated by a turntable’s cartridge to a level suitable for input into a power amplifier or receiver. It uses vacuum tubes to achieve this amplification and provide equalization, correcting for the RIAA recording curve applied during vinyl record production. This process ensures accurate and balanced audio reproduction from vinyl records.
The use of vacuum tubes in this type of preamplifier is often favored for their unique sonic characteristics, described as offering warmth, richness, and a pleasing harmonic distortion profile. Historically, tube-based preamplification was the standard before the advent of solid-state electronics. While solid-state options are available, the renewed interest in vinyl has led to a resurgence in the popularity of tube-based designs, prized for their perceived sonic advantages.
