When discussing or informing about HiFi as a subject we have to define what a correct reproduction is. According to our sound philosophy a correct sound reproduction should be as close to reality as possible.
This can easily be explained:
The only proper way of evaluating sonic performance is to compare it to reality. Anything esle is subjective. amd not possible to rate. The sound produced should in our opinion come as close to the real life experience as possible.
For this reason, the only authentic references possible to use would be comparing singing voices, acoustical instruments and live concerts and so on.
Comparing synthetic references such as electronic instruments, dinosours in movie tracks, heavily processed recordings and similar are not suitable since we have no real experience to compare them to.
When listening to a recording itīs essential that the listening level is correct because the human ear experiences sound very differently at different level.
