This phono stage is simply brilliant. It is still the current model in Sugden's lineup. British built, by hand. I am selling only because I haven't used it in about two years, as a result of an upgrade. I thoroughly enjoyed everything about this amp, from the quality feel of the switches and knobs, to the lovely blue glow from the operating lights, but most of all the beautiful sound it produces. Effortless and totally satisfying. Insert superlatives.
From the Sugden website: It has one MM and two MC inputs. 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 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.
