The guys who wrote SBR probably never tested it with (real)
metal. :-))
Those crackling sounds could be clipping distorsions - I think
someone said on vqf.com board that mp3PRO doesn't sound
good with nearly-clipped music. Since Jugulator is a newer
record, the volume is pretty high so there's lot of possibility
for clipping.
BTW Looking forward to hear Demolition. :-))

Since Vorbis currently sounds better then MP3 at 128kbps even though
it's not using joint-stereo I think that with JS, Vorbis at 96kbps will
sound just as good as 128kbps MP3. I bet that the low-bitrate optimized
Vorbis will sound as good as mp3PRO at any bitrate (or damn near at
least).
