Hedging, as usual!

Even though everyone seems to think the bits are all the same, either they aren't or Charles Hansen is a wizard. Either answer will please some and not others.

There's other possibilities. Are the bits being delivered to the DAC at the same time (for example)?

... or Charles is a reasonable normal person like you and me, and all what that entails.

Wow! You are the first to apply that term to me! (The report is that he did correctly distinguish the data, not imagined he did. The probability is tilted in his favor, so lacking details the most likely answer is that there was a difference. For his needs there was little to be gained by additional testing. Since the premise is not solidly defined added tests yield others little additional information.)

He got a bit irate at the suggestion that bit timing might be the explanation. I think the compound word "know-nothing" was used to describe people who said this.

Well, if it means that I can unravel a mystery, anyone can hurl any imprecation that they desire in my direction.

Why would you care what's delivered to the DAC - you haven't shown any concern about this in the past! just do your usual FFT analysis on the DAC analogue out - isn't this what is audible, not what goes into the DAC? Why the pretense at caring about bit timing?

[SY]

Two different issues.

[jkeny]

Of course it is
CH says he can hear an audible difference between playback software. You surmise that there might be differences in timing of the delivery of the bits to the DAC. So what are you suggesting that you will test?
