Absolutely. The hunting filter system has it's place, but the shifter
USUALLY provides better results (for voice / vocals and some
instruments like wind)
A small qualifier - in a live production, I would not use the shiffter
across a subgroup which contains a significant bass component (with
fundamental below 300Hz) like bass guitar or percussion.
This is because :
The mics used on these instruments will not require high sensitivity and
will therefore not be prone to feedback - therefore no benefit anyway
The frequency shift will be more noticeable on lower notes (particularly
when heard in isolation - ie, a bass solo). This is partly because the
percentage shift in harmonics in relation to the fundamental is greater
* having said that, a mild frequency shift of full program (e.g. from
CD) does not sound noticeable in background music applications
