It is important to exercise your Hi-Fi system across the full range of frequencies and amplitudes it may encounter in real life, and to this end the tones on this disc have been devised to cover the audio band from top to bottom, also ensuring that, for instance, high amplitude signals are combined with high speed ones. 

 

At the risk of oversimplifying a complex situation with a faintly absurd everyday metaphor, what the equipment needs is a good aerobic workout with some nice taut stretches and bends. In electronic terms, the required signal features lots of high-speed activity coupled with some high-amplitude excursions. All of these signals have been produced according to strict mathematical criteria so as to place the greatest stress on the important parts of a system - WITHOUT, it is important to note, endangering any part of it. If this disc is played at normal listening levels (volume control set as for your favoured listening material) there is NOTHING in it that will damage any normal music system. Raising the volume level higher will NOT improve the disc’s performance. 

 

"Burn-in and conditioning CDs for Hi-Fi systems are not exactly news. But IsoTek have taken note of all the various offerings and evolved perhaps the most sensible and complete version available. Simple, sensible and supremely cost effective, what more could you require?" Roy Gregory Hi-Fi+
