sorry but i completely disagree with that :P

a properly tuned front stage should not sound like a super deluxe boom box.
and most music you listen to is recorded in studio, not live performance.
even so, i know when i listen to mine, there is definitely no lack of depth or openness on live recordings.
it just sounds like you are having a slow transition in your tuning tastes and haven't gotten away from the rears yet.
also, having a pinpoint center should not deter from your imaging if its done right
