Why do some amps provide more output power when using a balanced connection?

I have an Audio Research LS 25 mk I which has a higher gain when using the balanced inputs and outputs. I just acquired a Schiit Jotunheim headphone amp that has a higher output with balanced as well.

 The increases are not at all insignificant.  The ARC preamp goes from 12db of gain with single ended up to 18db when using balanced.  The Schiit Headphone amplifier goes from 800mw to 3000mw ( with a 50 ohm load) when moving from single ended to balanced.

 Can someone explain why this takes place?

Al amazes me every time I read and try to digest some information he provides. Amazing, isn't it? And the best part is, there is ZERO bias in his responses.
Maybe we should have a "Almargopedia" section on audiogon :-)
