I'm about the only one around here that can handle that - sadly

. My point is contract someone who can understand and appreciate your genre and special needs and then let them do their thing. If you really feel you need to micromanage them then didn't you screw up and contract the wrong guy/company? I appreciate all kinds of music, from the primitive to classical to metal - and have a home system that's set flat so I actually know what it sounds like

. I don't even have subs in my car LOL. And that's what you'd be paying me the big (yah right

) bucks for.
Oh, and speaking of music from that era - there's always the question do you want it to sound like the record or how it would have sounded without the limitations of the recording process and/or the instrument amps of the days? I'd personally not run "hot subs" but would unconstipate the low end that the record had, especially if it was a longer song where they had to quash the low end into a 45. When I play it myself I tend to not play so many notes an octave up like many did on the original recordings - but only if the guitars are filling in the space thus vacated
