Should I re-rip?

dbpoweramp does a data and offset check.  If it says there was a match and no errors, you should not need to re-rip.  It's always good to examine the report after a rip.

As for format, .wav sounds best for most DACs.  Most people use FLAC or uncompressed FLAC because of the extensive tag handling.  If you don't care about this, then rip to .wav.  You can always convert back and forth without issues with dbpoweramp.

I ripped 4 tracks off Pink Floyd’s The Wall. I might be delusional but I thought the SQ of the WAV files was a tiny bit better than the FLAC rip.

You are not delusional.  You just have a resolving, properly imaging system I think.  I hear these differences plainly in my system.

These particular tracks are not the best to show these differences.  I have these tracks, but they are not in my playlists because they don't meet my quality requirements.

Let me understand this.  I just told you that you have a good system.  I just told you that IMO, The Wall tracks are not the best quality.  There are much better ones that show these differences, maybe not so subtle.

For this, you are rude to me.

Why don't you send me a thumb drive and I'll put 8 of my best test tracks on it.  I would do this even though there is no reason for us to "get even".
