There is much to debate on High fidelity and high end audio, from the right speakers to the components and of course the issue of cabling.
The main make up of a high end set up would be the amplifier equipment (pre amps and power amps are often combined) and the source is usually a CD player for high grade digital performance or a turntable for more pure analogue results (although lossless digital formats are coming in) and for those real assertive listeners - power conditioners.
Then what loudspeakers do you need to deliver the required sound? This entails looking into devices like the drivers (tweeter, midrange, woofer) and the crossover.

A driver in a real high end loudspeaker will either be hand made by the loudspeaker manufacturer or made by a driver manufacturer to a detailed specification. The frame will be cast aluminum or cast magnesium for high strength, low weight and low resonance. Cone materials will be carefully chosen after hours of testing to observe performance while playing a variety of music and by listening tests.
Small drivers are good at reproducing the highest frequencies we hear, but bad at reproducing the lowest frequencies. If you send low frequencies to a small loudspeaker (call it a tweeter) you can break it. So you want to send it only frequencies it can handle safely. The same goes for the big drivers (woofers), which don't behave well when they are fed high frequencies. So the crossover separates the high, mid-range and low frequencies into separate ranges and wires connect these 'ranges' to the correct driver. The crossover usually does its work with 3 kinds of components: resistors; capacitors; inductors. All of these have very large effects on the audio signal itself.
Voice coils are subject to endless research for different winding methods, types of wire and optimisation of the 'gap' to maximise the effectiveness of the magnet's field. The magnets themselves will tend to be handmade. Both increase the magnetic field strength inside the voice coil gap (a very good thing). Fitting of every component that makes up the speaker will be continually evaluated until methods are perfected.

The size and shape of the cabinet is selected to match the performance characteristics of the drivers and to achieve the desired response of the loudspeaker. The cabinet material will be selected for the particular loudspeaker design in question. Some resonance tuning will be done and care will be taken during the loudspeaker design process to ensure best performance levels.
The high end cabinet is normally made from mdf (a wooden finish). But mdf comes in a large array of quality levels depending on the size of the wood particles and the quality of adhesives used.

Then there is the cabling for HiFi installations, also known to some as interconnects. It is this area that probably opens up the most debate about the real impact high-end cables have on audio systems. There are claims that it is impossible to distinguish extremely expensive, exotic speaker cables from budget 12 AWG copper speaker wire.
One thing is for sure though and it is that the human sense of hearing is subjective and therefore it is difficult to define what is best unless it we are able to measure how electrical signals received by the ear are interpreted by the brain - suffice to say there is no definitive right answer here.

So whether your cable of choice is oxygen free, shielded, long crystal, resistant, high purity copper or silver speaker wire, why not let us help you with the rest?
