In my experience the D70 sounds like unicorns farting in a filed of rainbows - if you plug it into my system you orgasm immediately and then you see the face of Zeus.Like your persistence . It’s really simple, bring the two DACs at home and audition them in your system to find out which one is a better fit. In my system and to my ears the D70s won by some margin, particularly in the soundstage depth department. Please don’t ask what SS depth means and disqualify my comments. You share your own listening experience without being critical to others.
Does that sound like a statement fit for a forum that attempts to scientifically prove stuff.
If you qualify your statement by saying "my subjective opinion without any objective measurements or blind tests is that I like the D70 more - I have no proof that it does indeed sound different other than my feeling and my imperfect ears after sighted listening" then we're all fine - we all have many reasons to prefer certain things - to the point that we may believe they sound "better". I put better in quotations because, again, we don't all prefer the same thing.
So, you have not demonstrated even the inclination to provide anything apart from anecdotal evidence.
It's the same as commenting on vaccines because you know of a few cases with side-effects - while billions of others have had it and been fine - the numbers tell us what the truth is.
So for anyone reading this - there is no proof to these claims, this person has a preference that depends on a ton of things that have no objective underpinning.
