Some artists have high standards and wish to control the experience of their audience, they often insist on specifying the range of equipment they wish to use. Other artists go even further and tour with their own equipment to guarantee the level of quality they will use, especially as audio hire companies may not stock high end systems.
Many musicians have spent considerable time and effort composing their music and crafting their performance and this frequently culminates in tours. Their supporters have often spent a considerable amount or resourses getting to and attending an event, to experience the live show. We admire and respect this level of effort and commitment.
Selecting the appropiate system is crucial if you wish to convey every detail and nuance within the performance, ensuring the magic and emotion is felt by all those experiencing the show.
