Wiki states mp3 is a lossy format which is true, mp3 is generally considered a lossy format however when it created from WAV at 320kbps its pretty much lossless, or at least very close to it.
Generally that means the quality is extremely good and much better than your average mp3!
Also considering FLAC isn't very format friendly and probably doesn't work on IPOD, lots of people don't understand the difference in formats and conversion and would have trouble with them.
But all this is irrelevant in the light of the goodness of the sounds on this VA, these are some killer mp3s at the best possible quality!
We hope you enjoy the preview streams we have provided, they are only a small fraction of the fidelity of the downloads.
