| Another thing- if it passes a null test but still sounds wrong, then if you play it on a proper DAC it will sound right again.
As far as I know the only thing that can go wrong and still pass a null test is bad timing on the disc mastering causing poorly designed players to jitter. In that case the data is still there and any sort of playback that includes reclocking- even ripping the CD and reburning it- will 'fix the problem'.
You're probably looking at jittery timing and accurate data, if it seems like a big obvious problem but the data still nulls. That means at least you know it'll sound good again on proper kit :D |
