Vinyl is a passion for some people and that includes the design team at Sugden Audio. It is capable of the very finest musical experience creating a unique presence and atmosphere. The Sugden Audio Masterclass PA-4 phono stage is one of the most rewarding phono stages available at real world prices, helping you to enjoy your prized record collection for years to come. The Sugden PA-4 comes fully loaded with two moving coil inputs, a moving magnet input and infinite loading options as it can be factory set to match your cartridge exactly.

The moving coil stage is a ‘Class A’ current feedback circuit and the moving magnet amplifier a ‘Class A’ voltage feedback circuit incorporating the RIAA correction in the negative feedback loop. DC servo circuits enable direct coupling of the musical signal from moving coil input to final output. The power supply, which Sugden considers an integral part of the amplifier circuitry, is a ‘current shunt’ design with a specially designed voltage regulator to prevent rising impedance with higher frequencies. Constructed with components of exceptional quality, hand assembled on long-term stability gold plated circuit boards; the resultant performance is a phono stage of absolute transparency and natural sound.
