I'm just coming up with ideas for Amir or anyone with an Audio Precision Analyzer
. Audioholics has basically torn down the ideas of $5000 cables via measurements, and I want to see the truth (and extent of the truth) come out about how DACs sound from a sound signature perspective. Amir covers the same key points about a DAC to describe it's performance, but in the videos and written reviews that I've seen, there isn't a ton of talk about the sound signature (and maybe good DACs don't have a sound signature, maybe that is the point!).
As for my own testing for my own DACs, I've wired my Topping E50 (cheap but decent measuring DAC) and my PC audio into the Topping L50 headphone amp and need to switch back and forth on a routine basis. PC audio is really bad, so it's not anything special that I've been able to look down and notice why things sound so poorly. That being said, I honestly don't know how great a difference in "warmth" there would be between 2 actually good DACs, lol. I think we are on the same page about wanting repeatable and measurable data for whatever we are analyzing.
Also thank you Jim for the phrase by phrase breakdown of my post. I'm not really trying to make a point of argument, or even discussion, but rather a request to see these things measured.
