"Hollow" is a very subjective description, but as I hear it "hollow" 
is the result of destructive comb filtering as a result of poor mono 
compatibility, i.e. bad placement of mics. Generally omnis are much 
more forgiving than cardioids if one is departing from accepted 
coincident or near-coincident mic techniques. Maybe a different term 
than "hollow" is needed here. I use it when there is a loss in the 
200Hz to 500Hz region, & being a phase cancellation issue (as I've 
used the term) no amount of EQ can bring the warmth back.
