L300 Line Level Pre-amplifier
Following some fairly extensive r&d applied to line level amplification, pure sound will soon be launching two line level pre-amplifiers, L10 and L300. L300 has 5 inputs and twin outputs (2 pairs single ended and 2 pairs balanced via XLR). The circuit uses output transformers and a sophisticated full valve rectified, choke smoothed, regulated power supply including a 300B triode as the series element. L10 will also make use of output transformers.

A8000 CD Player
The pure sound A8000 CD Player was developed as a high quality source to be used with the pure sound range of amplifiers. It can also be used in a wide range of other systems with great success.
The A8000 is built around the SONY 213Q high precision mechanism, renowned for both its stability and reliability. A proprietary 24 Bit 192KHz D/A converter handles the data stream, which, once converted, is filtered using OPA2604 Op amps. The powerful output stage comprises a pair of 6N3 double triodes. Signal coupling here is via MIT capacitors while the output stage power supply utilises the German MCap capacitors.
The incoming mains supply is filtered by a choke regulated circuit which in turn feeds 8 separate regulated supplies each of which uses Silmic and Rubycon capacitors. These deliver power independently to various parts of the circuitry.
At switch on, the CD Player counts down for 20 seconds to allow the valve circuitry to warm and stabilise before the machine can be used.
The A8000 also offers the facility to switch the upsampling frequency from 44.1 KHz to 88.2 or 176.4 KHz.
The substantially constructed chassis includes a 10mm anodised aluminium front panel, high quality gold plated RCA sockets for L-R and digital outputs.
The remote control is a sleek, anodised design machined from solid aluminium.
Many CD Players using a valve output stage have an overly euphonic, almost ‘syrupy’ quality which compromises the reproduction of detail and drive. The A8000 has no such obvious characteristic. However, it does reproduce instrument timbre and dynamic range in a plausible way providing a lively yet unfatiguing presentation of music not dissimilar to that which can be heard at a live concert.
P10 Phono Amplifier - 660,00 Euros (iva incl.)
The P10 phono amplifier is the latest addition to the highly acclaimed Pure Sound product range. It is intended to meet the requirements of audio enthusiasts who still enjoy the distinctive strengths and high quality of reproduction that can be derived from vinyl records. It is compatible with moving magnet and high output moving coil cartridges. Low output moving coil cartridges will require the use of an additional step-up device or matching transformer. Full output from the P10 is sufficient to drive the line level inputs of any integrated amplifier or pre-amplifier.
The active amplification stages use double triodes in a simple anode follower configuration. The phono equalisation is achieved using passive components and can therefore maintain its accuracy over time without introducing the unacceptable levels of phase shift found in active equalisation stages. There is no negative feedback in the circuit.
The P10 features a particularly elaborate HT power supply. After the initial rectification and smoothing, the supply is split and two separate, heavily decoupled high voltage rails are established. These feed each half of the output valve while further decoupling of each rail allows the cleanest and most independent voltage rails possible to feed each half of the input valve. The absolute stability of this supply regardless of the demands made by the audio signal on the circuit, lends the P10 a stability and poise which allows effortless reproduction of the most demanding source material. The valve filaments are also fed by a DC supply thereby ensuring constant operating conditions for the amplifier.
The circuit makes use of close tolerance metal film resistors, polypropylene signal coupling capacitors and selected valves.
The gain of the P10 is 40 dB (x 100).
The P10 phono amplifier meets the very strict performance criteria required of all Pure Sound products and will give excellent results with vinyl records provided that it is used with appropriate ancillary equipment.
T10 Step-up transformer
The T10 mc transformer will be available very soon. The transformers have a step up ratio of 1:15 and a provision to adjust the cartridge loading between 30, 50, 75, 100 and 200 ohms.
