Getting most from MS..What tag program to use after itunes?

[wappinghigh]

Hi all. For years I have had my library in itunes. ~5000 tracks. Recently I converted everything to AIFF and exported the tracks using one of Doug's scripts onto a QNAP to use with Minimserver.

I'd like to get more out of Minimserver. So my question is what program do you recommend to improve tagging with my new library? I'd like to stay within OSX and AIFF if possible, but if I had to I guess I could convert all the files. But what to? I want the tracks to remain uncompressed. Is there a tagging program that actually runs on the QNAP? Is there something that tags AIFF outside itunes. What about Jriver for mac> Any other options?

Cheers and thanks for helping.
