I have one more thing to add about the checksums (this is more for the readers not the posters).
A matching checksum will always be better than anyone's hearing, it proves beyond any doubt that the files are absolutely identical in every way. So if you are hearing a difference the source files are not the cause.
e.g. I have 2 files called "Original.wav" and "Copy.wav", both checksums match.
D:\TEST\New folder\Original.wav
39548924 bytes
CRC32: b0296c49
MD5: 1672fa2df397b3b966a3dd1367a3809e
SHA512: 0779da516dbe48a867ce6ff7e475a6c76b705fa2dcfd033a7d2032fbecbb92a3cdb4b33f07da6338ba4cf56469815bf5c561f08c002d84f5f038badba6ad4154
D:\TEST\New folder\Copy.wav
39548924 bytes

If i attenuate "copy.wav" by -0.001 dB, not a single person would be able to hear this incredibly small change in volume level but if i look at the checksum i can tell the file has changed.

This is very helpful. Thanks for sharing that. Which program did you use to generate the three checksums for each file?
I did a few more blind listening tests and here I found that for some reason my dBpoweramp rips were being done to 320k MP3. I re-ripped a couple of discs and found that I couldn't tell a difference. Even when I knew what I was listening to, I heard no difference.
I am glad that you were able to attain clarity. However, as you know, the differences in my case were perceived on files that were tested both objectively and subjectively, so I still need to figure out what is going on.
Love an easy solution. Having just gone through a couple months reripping CDs with EAC I did not want to hear there was something weird going on.
Most people (at least those who voted in the poll) don't claim to hear a difference, so it may not be an issue for you. I enjoy the sound of both rippers, but usually prefer EAC. If this does not involve the actual software programs, I do admit that dBpoweramp is much more pleasant and efficient for me to use.
Let's hope that soon I am able to ascertain the true cause of the problems I am experiencing, so we can all move on to bigger and better things!
