Ha, I love how these engineers frown on new ideas just to end up implementing them later. Once you've been taught what you can't do in the studio it's hard to break those rules.
I think these days mic pre-amps you are what you want to own. It sounds like The Hydeouts are already on the right track for a killer sound. But these days, since we aren't working often with analog tape, it's best to already give some warmth and compression in the recording process before it hits the hard disk recorder. Another trick I've done to fix weak vocals is to run a standard vocal signal back through an guitar amp and record that on a separate track. The mixing of the original and the amplified can really produce a punchy yet fucked up sound. Also another dirty trick if you don't have a good reverb unit you can send your voice through an amp you can set up a condenser mic set up to record on the other end your room or hallway. You can mix your original track with this room mic track to give some space to the vocal and get a little room feeling with some amplifier distortion.
