How many systems are built the same, i.e, same Brands Models that are used for a particular role throughout the audio chain - very very few.
Nearly all systems built are unique in how they are put together.
How many individuals have a broad experience of being demo'd audio ancillaries where their assessment is able to assist another in creating a experience that is for them an improvement and a attraction worthwhile maintaining - not many of those either.
How does seeing an image of an individuals set up in place of a list make for a better evaluation?
An image might show means of s supporting structure and maybe even the room used for the system.
A poor method being utilised as a support structure, or a room that is not looking suitable for a Stereo Replay can be commented on, but I don't see much more that can be addressed through looking at an image of a Audio System.
