The Cambridge 640A V2 builds upon the impressive features of the previous model 640A resulting in a quality of performance you could expect from amplifiers costing considerably more. This development provides true audiophile levels of sound reproduction and reaffirms the Azur marque as a leader in this category.

Cambridge Audio continues to meet the needs of audiophiles at all levels and the 740A is no exception. The Azur 740A offers true hi-fi quality but at a fraction of the cost. Indeed the technology in the 740A is normally only used in products costing many times more. The 740A uses a further development of Cambridge Audio’s trusted amplifier topology. Two pairs of extremely high current output transistors per channel allow the 740A to drive almost any speaker with ease and ensure excellent bass response and dynamic control.

The 740A also includes support for multi-room use. By plugging in one or two external Cambridge Audio Incognito keypads (or Incognito active speakers) and a power supply unit, the 740A can become the hub of a simple multi-room system. In addition, Control Bus Input/Output and IR emitter input are provided to make it easy to integrate this unit into custom installation systems if desired.

Cambridge Audio breaks new ground with an entirely new class of amplifier in the shape of the 840A which marks the zenith of Cambridge Audio’s critically acclaimed Azur line-up.

Embracing Cambridge Audio’s patent pending proprietary Class XD™ technology, the 840A brings together the quality of Class A amplification, the power economy of Class B designs, and most amazingly of all, avoids many of the distortion pitfalls inherent in Class AB designs.

Completely separate pre-amp and power amp toroidal transformers and circuits make the 840A effectively a pre and power amplifier combination in one chassis

Another enormous benefit is its ability to integrate seamlessly with a home cinema system. Fixed level inputs allow the 840A to provide the front channel amplification to systems which use an AV receiver. The receiver continues to provide centre and rear amplification.

In addition to this innovative technology, the 840A uses an extremely sophisticated resistor ladder and relay attenuator for volume control and the same high quality relay switches for input selection. This enables high isolation between inputs, very accurate channel balance and leaves the amplifier completely free from the distortion associated with conventional semiconductor switching and volume control.

Immediately noticeable is the new cosmetic appearance along with the improved SR-5 remote control handset.

NAD quality is much in evidence with the NAD C-352 Stereo Amplifier. It offers increased power and versatility. It delivers an extremely high standard of performance and value in integrated stereo Amplifiers. Like all NAD amplifiers, it is built on the same ‘platform’ as the C-320BEE and has all the unique NAD features like ISC, Soft Clipping and off course a high-current amplifier design with a Toroidal Transformer and which in the case of the C-352 outputs around 80 Watts of full bandwidth power into each channel.

NAD has an enviable reputation for creating some of the best performing budget amplifiers of all time. The lineage is impressive, all the way from the 3020 of 1978 to the current C325BEE, with many “Best Amp” awards and 5 Star reviews along the way. As loudspeaker quality and performance has continued to improve, especially at modest price points, NAD felt that there was room for a lower cost amp that could take advantage of these speakers; creating a new entry point for serious musical performance. Introducing the C315BEE Integrated Amplifier.

Exquisitely built, this Australian made amplifier takes the signal-direct form the source via silver plated solid core internal wiring, producing stunning clarity, depth and space. The sound is pure valve, smooth and clear with the added dynamics, speed and low end response of solid state only found in components costing far more.

The third generation of Brio the Brio 3 now boasts a modified power supply and up-rated power transformer.

The increased power output (49 watts per channel into 8W) of the Brio 3 greatly improves control and musical performance over its predecessor.

Rather than having unnecessary gadgets and frills usually found on products in this price range, the Brio 3 utilises the highest quality components to achieve the best sonic performance.

The output amplifier is built around a pair of Sanken 150w Darlington output transistors and an electronic circuit protects against shorted speakers and reactive loads of 1.7W or less.

The power supply uses the new generously rated toroidal transformer and 10,000µF smoothing capacitors that provide enough current to drive the hardest of loads.

Substantial power (100 watts x 2) and a damping factor of 400 assure that the Rotel RA-1070 has precise control of all but the most demanding loudspeakers. The high capacity power supply features an oversized Rotel made toroidal transformer and British-made BHC slit foil capacitors. Convenience isn’t an afterthought either. A separate Record Out selector adds flexibility.

The Rotel RA-1062 is the evolution of Rotel’s highly regarded RA-1060. The design team spent hundreds of hours evaluating individual component performance from input to output. Chief among these improvements is the UK designed and manufactured T-Network power supply capacitor. These premium grade components follow the tradition of our Slit Foil capacitors by incorporating tiny perforations in the capacitor foil to reduce distortion.

Rotel has established an enviable reputation for the audiophile performance of its amplifiers. The RA-03 looks to expand upon the 02 Series success. The pre-amplifier section of the RA-03 is based on the award winning RA-02, which is combined with the power amplifier section of the critically acclaimed RB-03 power amplifier. As with all Rotel amplifier designs the circuit board layout employs techniques critical to achieve audiophile sound quality, utilising components selected for both their technical and sonic qualities.

A thoroughly modern classic, the Rotel RA-02 adds the convenience of remote control to one of the most praised integrated amplifier circuits ever developed. Power output (40 watts RMS x 2) is more than adequate for all but the largest rooms. High damping factor assures positive loudspeaker control.

The Rotel RA-01 Amplifier traces its lineage directly back to the famed RA-820, Rotel’s signature entry into what was then a radical new product class – the "affordable high end" component. Indeed, the RA-01 redefines the relationship between value and performance with circuits executed with a rare level of care and precision. The RA-01 provides fatigue-free musical fulfilment from up to five line-level sources and one MM Phono cartridge.

Full Floating and Balanced Circuit Design Achieves for the First Time the Full Potential of Analogue Amplification

An entirely new floating and balanced power amp that, by using power transistors with the same polarity that are not complementary, achieves complete symmetry of pullable operation at the output stage and permits full balanced transmission (amplification) from the input jack to just before the speaker jack ó a capability that has long been the dream of audiophiles.

Full-Stage Balanced Signal Transmission

The A-S2000 achieves fully balanced signal transmission from input to output (balanced design refers to the use of two signal conductors that have equal impedances to ground). Balanced transmission is capable of canceling noise produced internally and externally, and so is considered to be an ideal amplification method, eliminating the sound quality degradation caused by noise.

Floating Balanced Power Amp

The floating balanced power amp configuration is completely different from the pure complementary circuit design that has been the mainstream of Hi-Fi amps for nearly 40 years. It adopts an output element having identical polarity on the plus and minus sides of the output stage, with both sides having their own power supply and feedback, thereby achieving total symmetry of pullable operation at the output stage. The power supply unit has four floating elements (no restrictive grounding connections), two for each channel, so plus and minus are completely symmetrical.

Fully Balanced Control Amp

To achieve fully balanced transmission, all audio circuits except for the phono equalizer are balanced. The line amp also uses a balanced configuration for its volume and tone circuits, achieving fully balanced transmission from the XLR balanced input jack to just before the speaker jack. Additionally, the output from the unbalanced RCA input and phono equalizer undergoes balance conversion internally.

Parallel Volume and Tone Controls

To ensure ideal fully balanced operation, the volume and tone control systems must be extremely precise. Conventional analogue volume systems suffer from gang error, and cannot achieve sufficient accuracy, even when using high precision parts. Therefore, for the A-S2000 we developed a unique method: canceling out slight precision differences by the parallel operation of three high sound quality digital volume ICs for each channel and operating the system with an analogue encoder. When using the bass and treble tone controls, each of the three volume elements is applied in succession, and during tone default, three equivalent volume elements for each channel are used for volume adjustment. This ensures the best sound quality during both tone control and default operation.

Power Supply

The A-S2000 has four large capacity power supplies for the power amp that are completely isolated from ground. Shunt type local regulators that prevent degradation of sound quality by amperage fluctuation ensure a clean and stable power supply for the preamp.

Symmetrical Construction

The A-S2000 has a completely symmetrical construction intended to achieve the ultimate in integrated amp left-right separation, equal to that of separate amps. A central reinforcing bar ensures that the chassis is rigid and stable.

Specially Designed Feet

The extra-heavy feet provide a choice of two bases. You can leave the round, flat neodymium magnets in place or remove them to rest the amplifier on four single points. The feet are also height adjustable. They ensure stability on any surface, with superior vibration damping.

Headphone Amp for Low Impedance Drive

The fully discrete, high performance headphone amp is compatible with low impedance drive. Its pure and powerful sound quality is best appreciated with high quality headphones.

Discrete Phono Amp

An extremely low-noise phono amp plus a dedicated MC head amp ensure excellent musical clarity and imaging with both MC and MM phono cartridges.

The AS-2000 comes with a five year warranty.
