And this is a tautological debate now. Without measurements you can't really expand on "good" or "better" and (unfortunately for us) your assurance means nothing (it's too inherently rooted in your own perception; which nobody shares with you - you may be spot-on for what I, or someone else, likes, or you may be completely out in left field; it's not any sort of judgment of you, because your perception works for your needs) - the science disagrees as a result. Anyways, glad to hear someone else enjoys their SA5000!
It's questionable if you would hear a difference in amps and source if you have Faux-SA5000s... and whats all this about Science? I remember back in 09/10 all the new guys saying there are no benefits (on paper) to be had after the Fiio E7/9, now needless to say those same members are running thousand dollar setups. It's easy, perhaps arrogant to claim there are no benefits to be had from any other equipment than headphone when you haven't actually heard them.
