I guess the reason I blast my inputs as loud as I can before clipping is because I can. It's just me and I have plenty of time to to redo tracks or reset levels if something clips. Usually though once I set up a track/channel and jam out through it a bit I never go over from then on.
Now if I were in a LIVE situation and/or recording others and/or was pressed for time/unable to sit there and tweedle around so much then I'd definitely bump the inputs down more than need be just for extra clip protection. Things generally tend to get louder after sound level checks so a 3db or more buffer would be how I'd go just to be safe.
And of course I use my hardware as my first reference/line of defense against clipping. On the mixer if I'm using one or using the input trim on the interface if I'm going DI. Clipping outside the box (before/at the AD converters) is something nothing can be done about after the fact.
That said... I guess if there is some kind of sound quality benefit to turning down a bit I'm open to it. I've just always tried to get any out of the box signals as strong as I can because it seemed like the right thing to do and I HATE having compensate for low levels after the fact (I used to get that a lot before I knew what I was doing).
Most of what I do is DI guit and bass work anyway though or using line in from outboard gear. Then I add emulators and whatnot. So maybe this stuff doesn't affect me as much and if I did more mic/room recording the benefits would become apparent.
Really I've mostly cobbled together my methods by simply experimenting with things over and over again while occasionally adding little techniques I've read here and there or been told by my buddies here (thanks doods).
I think I'm getting close to maybe, sorta, kinda getting some decent/consistent results. I'm actually FINALLY about to start screwing around with some old band projects I've been putting off because I didn't want to make them teh suxxors due to incompetence.
Now I believe I can pull it off properly... all thanks to this place and a MOUNTAIN of reading, watching, studying and experimenting.
Of course... it could still all end up teh suxxors but it's time for that proverbial pot to get pooped in or remove my scrawny buttocks from it.
