Sugden Masterclass PA-4 MM/MC Phono Preamplifier
type: Product
description: Sugden Masterclass PA-4 – Class A MM/MC Phono Preamplifier The Sugden Masterclass PA-4 is a dedicated phono preamplifier for serious vinyl systems, combining two Moving Coil inputs, one Moving Magnet input and carefully engineered Class A circuitry. Designed for listeners who want a refined analogue front end with practical cartridge flexibility, it preserves the natural character, atmosphere and low-level detail that make vinyl playback so rewarding. Overview The PA-4 provides three separate phono inputs: two for Moving Coil cartridges and one for Moving Magnet. This allows more than one turntable or tonearm to remain connected, making it particularly useful for advanced analogue systems or listeners who regularly alternate between cartridges. Sugden uses a Class A current-feedback circuit for the Moving Coil stage and a Class A voltage-feedback circuit for the Moving Magnet stage. RIAA correction is incorporated within the MM stage’s negative-feedback loop, while DC servo circuits allow the musical signal to remain directly coupled from the MC input through to the final output. Key Benefits Flexible cartridge support: two MC inputs and one MM input accommodate a wide range of turntables and cartridges. Selectable MC loading: front-panel selection between 100Ω and 470Ω supports effective matching with many Moving Coil designs. Low-noise analogue architecture: dedicated Class A gain stages are designed to preserve subtle musical information. Dual line outputs: two outputs allow convenient connection to more than one amplifier or recording component. Long-term ownership: gold-plated circuit boards and hand assembly reflect Sugden’s emphasis on stability and serviceability.
