Thoughts

The rejection ratio achieved is described in minus dB. The CMRR of a system

follows the formula 20Log(Voutput/Vinput). In other words a CMRR of –40dB means that all garbage entering the unit will be made 100 times smaller. The

piece of equipment with poorest CMRR will effectively determine the hum and RFI level of the system. Effectively the weakest link in the chain. Highest quality audio systems should quote a CMRR figure of –80dB or better.

Positioning of your source equipment (tuner, video, disc, tape, record, decks) is important. To avoid airborne frequency peaks, place them well away from your loudspeakers and not in the corners of your listening area.

Loudspeaker placement is a controversial issue; suffice to say that room corners are generally the worst situation. Everything which constitutes your listening area, including the materials used in its construction, will affect the sound itself and the sound stage created. Equally, you have to live with your system and therefore compromises will have to be made in line with your particular priorities. The best advice we can give concerning the choice of loudspeakers is, establish clearly in your mind your requirements; listen to many makes and models, and if at all possible audition your preferred choice in your own listening area and trust your own ears.

When matching speakers to amplifier wattage – ordinarily, the amplifier should have a continuous RMS output power rating the same as or higher than the speakers at the same impedance rating. For example, 350WRMS, 8S speakers driven by a 350WRMS at 8S amplifier is not as ideal as 250WRMS, 8S speakers driven by a 350WRMS at 8S amplifier.

350 Watts is twice as loud as 35 Watts, not ten times as loud.

Perreaux equipment is designed with substantial headroom built in – that is, the reserve necessary to reproduce musical peaks without clipping.

High fidelity systems are an investment deserving of careful thought and personal time. Your preferences, priorities and constraints will dictate the parameters of your purchase, your ears will tell you what is the right choice for you. Our experience tells us that the bitterness of dissatisfaction lingers long after the fragrance of cheap price is forgotten, hence our use of the term – investment.
