Obviously I was deliberately making a statement that I couldn't back up, but I will tell you this, if I did have money, I would happily travel down to meet you and conduct the blind listening tests with you. I am willing to bet that you have never conducted such a test so hopefully if that assumption is true you will at least be fair minded enough to consider that you don't actually know from experience whether or not you can hear the assumed differences under proper testing conditions.
You should consider that in this community and others there have been brave and open minded members over the years who have actually participated in proper blind listening tests and not been able to tell the differences between DACs, and these are experienced users who were curious, not with an axe to grind. Regardless, no point in me going on about such things so I will cease and desist.
The only thing that I will add is that while this community is the very best such Internet community, and one that I love being a member of, it does have a poverty of any objective measurement efforts for DACs and amps, and that is fine, head-fi is not meant to be that type of community and I get that and support that. However, if people are interested in digging into the actual science there are communities such as audio science review where the backbone of the community is objective measurement of such devices. We need all of the communities so my saying so is not to pronounce one community as better or more valid than the other. I actually think they are complimentary and work together to promote and improve the hobby for audio enthusiasts.
