When you're sitting right in front of a loudspeaker you're in its near 
field. That causes what you hear to be dominated by direct sound from 
the loudspeaker. The loudspeaker(s) excites the room, but you're so 
close to the loudspeaker that you don't hear the room response. Most 
recording studios have a pair of high quality loudspeakers mounted on 
top of the console for exactly that purpose. They also have a larger 
pair that DOES excite the room.

Anechoic chambers are TEST environments, they are lousy listening 
environments.

All it takes for excellent receive sound quality is a decent pair of 
headphones. The CM500, Sony MDR7506, and Etymotic Research ER4 are 
excellent choices. There are other good choices, but these are well 
established, widely available, and not expensive. All are VERY 
comfortable for LOOONG contest weekends (although comfort in the ER4 
depends on matching the ear piece to your ear).
