Pure Sound A30 Valve Integrated Amplifier

Very good with original packaging

Pure Class A line only integrated amplifier

The well-received Pure Sound 'A30' Integrated valve amplifier offers tremendous value for for money. The design smacks of quality from every angle and is a joy to listen to pure and simple.
The man behind Pure Sound is GUY SERGEANT of Audio Innovations fame, so it should come as little surprise the products sound as good as they do for what is a relatively reasonable outlay.

PURE SOUND A30 (line Integrated)
"The pure sound A30 amplifier was developed to meet the demand for an affordable Class A amplifier that would be compatible with all types of loudspeakers. The A30 is a line level integrated design that allows for the selection of up to 3 different source components and control of the volume by a high quality ALPS Blue Velvet potentiometer. Class A operation was chosen because it gives lower distortion and a more relaxing, natural sound"
The amplifier uses the very robust Electro Harmonix 6550 output valves in an Ultra Linear Push Pull configuration. This arrangement gives a combination of power and clarity that is difficult to beat. The amplifier uses an Auto Bias system, which means that replacement output valves should be fitted as matched pairs. There will be no need to reset or monitor bias conditions.
Very high quality components are used throughout including selected carbon film resistors and SCR polypropylene capacitors. The power supply makes use of twin valve rectifiers and choke smoothing.
The output can be configured for use with 4 or 8 ohm loudspeakers.
The output stage can also be switched to triode-coupled configuration. This further linearises the operation of the valves at the expense of some output power. It may be preferable with higher sensitivity loudspeakers.
The A30 may also be used as a very high quality stereo power amplifier if the volume control is turned up fully.
When partnered with appropriate ancillary equipment the A30 is capable of very satisfying performance.
The valve rectifiers used keep the high voltage power supply clear of the noise that can be introduced by silicon rectifiers. A substantial choke is also incorporated to keep the power supply impedance low.
The output transformers also give extremely wide bandwidth allowing very solid low frequency performance as well as exceptional reproduction of timbre.
These design features combined with the use of high quality passive components, octal based input and driver triodes and an elegant but simple internal layout results in an amplifier which sets a new benchmark for performance, build quality and value.
