If you make it a controlled abx - I pretty much guarantee the apparent differences you hear now will all disappear.
As you already have Foobar 2000 - you just need the abx plugin, and you need to apply replay gain to the tags to volume match them. So take your CD, rip once to lossless, and transcode that rip to MP3 320 (again - ideally use latest LAME encoder). Use the abx comparator - tick the blind box during the test so you can't see the results real-time - and make sure you run at least 15 iterations on the same track. Post the results.
It's an exercise that is worth doing - as it is actually enlightening to really know what we can actually distinguish. For me - it also makes listening from my iPod Touch G4 more enjoyable. I know the tracks are AAC 256, I know the iPT4 is essentially flat and transparent (a really good dap actually), and I know that I cannot distinguish AAC256 from lossless. So placebo can't get in the way at all - and I am never left wondering if I can squeeze any more quality out - ergo ..... I enjoy the music more.
I havent done abx yet, since I had the daunting task of locating the lame encoder within foobar 2000. I googled for the lame encoder, downloaded it and unzipped it into a folder. When I opened Foobar I could not locate the 'converter' tab. Some sites posted screen shots of how to locate it, but my version of foobar (latest version) had it so complicated that I spent close to 1.5hrs wondering if the initial install up was right.
Anyways, I took my CD, ripped a track to MP3 320kps using LAME in foobar and listened closely with the original CD and my observation was.... There was NO noticeable difference in either formats.
Then I took the same track in FLAC & compared it to the new 320 LAME and still there was NO difference.
Result was original CD = FLAC = 320 lame
I Thank You for your time and post and this little exercise in helping me to understand the difference

I thought this was the case until now, that ALL mp3 software that encoded to 320kbps would sound the same. But its not the case for iTunes. There is a huge difference in sound to an mp3 encoder vs lame

You are absolutely right about this! Thanks also to you for your time & post for letting me know about this!
Now I have 15+ years of CD collection re-ripping to be done and all this time I thought I was listening to the best
