Reply to Convert Flac to m4a

I'm believeing of converting all my flac files to apple lossless m4a, maybe that file is better supported in Traktor pro regarding the storage of the traktor data in the file itself rather than in traktor itself...

Anybody got any info on this?

Also i know converting is always loosing a bit of quality, but since this are lossless compressions... is there any quality lost then?
I would believe not, isn't it just the same as a data file going from zip to rar ?
