I see that Audio Diffmaker was suggested but don't see where the OP or anyone else had tried it, with the sound card outputs of the two identical files.
I don't think anyone will be much interested in a test like this unless they first of all hear a difference.
I thought we could all join in the fun and run a parallel experiment.

2. Listen to all three one-minute clips as much as you like.
3. Complete this survey.
All clips were ripped from CD using EAC in accordance with the original poster's description.
At least one clip was ripped in safe mode.

They are trimmed from identical CRC files. The PCM data is the same, or should be.
Is that what we're trying to discern? -if two identical files sound alike?
I can post the identical files, but they aren't trimmed so will be a larger download for everyone.
I believe you can use Audacity to do the trimming with accuracy down to a single sample.
Yes indeed! Threads like this remind me of my new favorite TV show "Finding Bigfoot." No one ever finds anything, but great hi-jinx ensure. It's amazing that you can make an entire TV series (or thread) out of nothing. The ghost hunter shows are exactly the same. "Wait! Did you hear that?"Serious, moi ? I was having a bit of fun there
Nothing personal Erin, but your claim is a lot like claiming to see a Sasquatch. Finding one would be amazing, but the evidence is still so thin it can't be taken seriously. I know you meant no harm and just wanted to report what you heard to the rest of the audio community. You'll have to excuse us if we seem incredulous.

But had the claim not been so 'controversial' you would not have been incredulous. I see this sort of thread as direct evidence that claims based on listening are all questionable, if not outright null and void. You are able to dismiss this one out of hand, because you know it's wrong, but if someone claims that digital sounds harsh compared to vinyl, for example, everyone around here laps it up, despite direct evidence that audiophiles can, and do, hear what they want or expect to hear.
Audio DiffMaker found a very slight difference between track A and track B. A&C seem identical. You may have been off a sample or 2 when you trimmed them, that's all.
Thanks, Pano
I'm uploading the full songs now, just so there can be no doubt.
The full songs are up now. It's a 3-5 minute download.
Have fun, lads.
Do it for science!

EAC in safe mode uses the default Windows drivers instead of the custom one included in EAC.
Basically you try to prove that EAC custom disc drives suck compared to the default MS ones? Considering that the driver in XP is different from Vista or Seven and the fact that x32 are different from x64 you are still required to say which version of Windows (and SP) you used and on what motherboard (since that makes a difference too).

Re the sample DLs.
Are 2 out of the 3 files identical ? It would be most unfair to have 3 different files and expect people to say which sounded best, especially after Zipping,Unzipping,saving to a computer which could be a mediocre laptop or a high quality desktop, and degradation due to Servers and numerous transmission hops.Are people using analogue Out from a soundcard, or via a high quality DAC ? There are far too many variables here, especially if some people look at the files with binary editors etc, for an hour or so, decide there can't be any differences, and then have a quick listen.Expectation Bias works both ways ! 2 out of the 3 files should be stated as being identical.Even most participants correctly nominating which 2 files sounded the same is of statistical relevance.
