It seems very easy to evaluate a camera or a monitor screen with regards to how realistic it is in capturing the likeness of the visible world. Take a snapshot, or record a short video clip using a camera of your choice, play it back on your TV or on your monitor, and it will be plainly obvious whether the reproduced image is faithful to the real object (in terms of proportions, visible details, texture, colors, etc.)

Things are for some reason not that easy with audio. Take a recording device, point it to the live performers, record the performance, and then play it back on your stereo. You'll realize that it's a challenge when it comes to assessing how faithful to the real sound the playback gets.

Maybe this is so because of the fact that music is fleeting? While a physical object that we just took a snapshot of still remains present, and we can compare its representation on the screen with its actual presence, we can't do that with music. Once performed, the performance is forever gone.

Not always so easy with the video side of things. Take a couple of interior designers and ask them about the 'colour' and you will probably get two very different opinions.

My Wife is one such and where I am quite happy with that cream colour, she will get fifty (I kid you not) matchpots made up from various companies and compare them for weeks in different lights, at different times of the day and up against other colours before coming to her conclusion.

Similar problem talking to experts about colour saturation, sharpness, tonal balance and I don't know what else. When I used to sell expensive projectors and screens to Home Cinema customers, we used to pause a picture in one spot and compare endlessly back and forth whilst the customer chose the best picture. To me it mattered not a jot but it was life and death that one projector was slightly bluer than the other to some of our customers.

It's all down to personal taste in the end whether it's audio or visual. IMO
