Recording artists do not have a meaningful, trustworthy or easy way to compare the sound of the equipment that is available in the market to make their art. There is no hub to easily and quickly compare audio equipment in a natural way. The process of audio gear comparison before purchasing is scattered, time-consuming, very biased, subjective and heterogeneous. Most of the buyers cannot make an objective comparison looking at the frequency response curves so they surf the web looking for information. They will find different information about each piece of audio equipment in different places, making the process unstructured and difficult to compare. In a nutshell, they will not find a homogeneous way because there is no comprehensive database of objectively reviewed audio gear. Therefore, they can’t distinguish biased or salesy sources from trustable ones.
