Hi Mike. I bought the audiophile ultra-pak on a 500 GB USB hard drive. Since you have "everything" the only files you would be concerned with for audiophile versions would be the Real Tracks; you already have everything else as good as it gets, I think.

Can you hear a difference? Yes, I certainly can. However, it's pretty subtle. The main difference is clarity - the lack of those little artifacts of compression. My home studio equipment is pretty good, and that helps; on a boombox or in a car, you would probably never hear a difference.

In at least two other threads last month, several of us commented on how these audiophile versions work in a mix. Mac said it best, I think, when he mentioned that noise is additive in a mix. If you are serious about selling a mix made with Real Tracks, I think the audiophile version is worthwhile.

About the comment that the audiophile files are unprocessed in the sense of no reverb, in my opinion this is not true. The audiophile files are simply the same sound as what was then compressed into the WMA files for the non-audiophile version.
