Hello mozartfan,
Apparently, you seem to have an absolute inclination and preference toward absolute thinking in this audio hobby. I've learned through personal experience that claims of audio absolutes are of little merit, are rarely reliable and cause the closure of an individual's mind to new ideas, discoveries along with a voluntary forfeiture of the very process of continued learning and growing itself. Well, good luck with that.
