Not at all, because some people will perfer systems with certian specs and others will not.

I'm suggesting that once you find out what paramitors you like in a system and the subjective impression they leave you with, you can choose Hi-Fi bassed on informed decision.

For example if you find that systems which are time-cohearnt nearly always make you feel involved in the music, that is has better soundstage and imaging, you can look for systems that are time-coheatant rahter than just having to listen and see if it has that mysterious factor of 'involvement' - which would be differnt for each person anyway as they find difefrnt things involveing.

Its the same way that a good designer of equipment can be asked to design an amp that sounds this way and that and they know what paramitors will give it that sound (at least to their ears).
