djones, my intention wasn't to single you out with regard to vinyl. My point is that the issue of specs doesn't come up when discussing analogue, it's a given that there are distortions. Most likely vinyl is pleasing to the ear due to even order harmonics.
DACs that can produce these harmonics, such as R2R, may be considered organic, natural, or warm. It's an alternative to Dacs that have an analytical sonic signature. But not necessarily; I had a Schiit Gumby Multibit that was neutral and very revealing. So much so that it was fatiguing to listen to.
And a tube Dac can be warm or neutral depending on tube selection.
My point is to listen to a component. Test results may indicate distortion or nonlinear specs on a scope. Many of these results may not be audible.
As I stated earlier, I like Audio Note's philosophy; specs don't matter as long as it sounds good and it's faithful to the original recording.
