Admittedly I'm a huge fan of Chango but I'm surprised that anyone could find this to be bad production. I haven't listened to the stream but the high quality mp3 is amazing.
I'll say this about it.
His electronic samples and effects SOUND great but are vastly overused in the music he produces.
His guitars EQ or modeling needs to be changed, incorporating more low end and just a tad more gain to sound "beefy" and less tonal.
He needs a quality drum kit to replace his stale, clicky samples.
Some renovation would do his studios wonders
