kosst- There are psychological, emotional aspects- human aspects when listening to music. All music reproduction has a leaning towards warm, analytical, rich, lean, forward, recessed, etc, etc. We decide on an individual basis what we prefer, otherwise we would ALL agree on what amp, speakers and/or audio equipments sounds the best! Not everthing in audio can be measured, and stated to be superior. Then of course, do we all have the same level of hearing abilities? Of course not! One’s opinions should require them to have the ability to respect other thoughts on the matter. Otherwise they may come off as closed minded know it alls. That can lead to attacks on others who may have valid opinions.
