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?

I use balanced headphones .....balanced from the preamp through the balanced amp and then balanced to headphones.  The sound is quite wonderful...and recommended.  Your question is of less noise and increased clarity with balanced configuration.
