So I'd wonder if a null test could ever reveal small differences like this. I also wonder how precisely you can line up to match the audio before doing the null? I don't use the editors all day at work like some of the guys, so I don't know how easy it would be to get perfect alignment. Analog null doesn't have this issue and the resolution is much higher for sure than 44.1/16!
PS...I thought at one point that the CF test was to compare FLAC files versus CDP redbook. But maybe I was wrong....
Every recording/playback method has it's drawbacks. Better equipment helps as does a better/cleaner source and more data. Think a R2R machine playing at 15ips vs. a cassette or 8-track tape. Or fer you youngins CD vs SACD.
Dr. Shockley postulated that an LP contained approximately 50GBs of data. At that time however, there weren't any techniques available to record and store the data in a cost effective form. Now we have BR that can store that much and at really high sampling rates. My computer's audio card has many more times the resolution of a CD, so you'd think that would be audible.
On the other hand, I've got some CDs that sound GREAT.
I reckon we'll see in roughly 80 days.
