MASTERCLASS PA-4 PHONO AMPLIFIER
Vinyl is a passion for some people and that includes the designers at Sugden Audio. It is capable of the very finest musical experience creating a unique presence and atmosphere. The PA-4 is one of the most rewarding phono amplifiers available at real world prices helping you to enjoy your prized record collection for years to come. The PA-4 comes fully loaded with two MC inputs, an MM 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.
