i have to admit though, the difference really aren't the huge to me... granted I only listened on computer speakers but it doesn't take $$$$ monitors to hear what a 2BUSS comp is doing to transients when a/b'ing like this.
the trick for me is to listen very closely to what's happening with the SNARE.. that's what i'm always listening for.
and on the topic of 2BUSS comps, I'm demo'ing the Duende Buss Comp and I fucking LOVE ITTTTTTTTTT. Didn't dig it at first because I am so used to the Waves incarnation and The Glue but JESUS they got it RIGHT!!! it's like instant GLUEEEEEE and SHEEEEEEEEEEEN. well, when setup correctly...
