pretty much the title...

if I have 320 cbr MP3 files (I'm going to assume all from lossless sources), would converting directly from 320 cbr to v0 or v2 result in lower quality than if I have converted directly from lossless to v0 or v2?

Yes. There is theoretical/mathematical loss every time you encode MP3. However, you may not hear any difference.

Since you don't have the lossless originals, there's not much point in asking the question... The more important question is, "Will I hear a difference between the 320 and a V0/V2 conversion?" You'll have to try it for yourself to see if you can hear a difference with your files.

If you have a need, or a good reason, to re-encode.... Just do it and live with the potential quality loss. If you don't have the need, just don't do it...

I don't like making lossy-to-lossy conversions, but sometimes I don't have a choice (I usually do have the option of using high bitrates and I never notice any quality loss).
