Did you encode these at 448k from the uncompressed master .wav file? :)
Satanika upmixed the stereo file I sent him (flac, for ease in uploading) using the Foobar2000 plugin ATSurround, into a multichannel wav and added in the custom LFE channel, then encoded the result to 5.1 AC3 at 448 kbps. So in short, yes. ;)
It sounds fantastic.
Edit: the download links are at the bottom of the previous page, in case anybody missed them.
