can someone explained balanced amp and headphones in laymens terms. does it effect sound quality greatly? also will a balanced amp run unbalanced headphones?
In your typical normal headphone, the current the drive the speaker inside the 'phone is connected to the source by two connection: one carries the power (+) to the drive, the other is the ground (0V) - this is much like the main socket on your wall. In laymen's term, a balanced headphone is a 'phone where the ground is replaced by a negative signal (-) that is the opposite to the (+) signal. This means the total voltage on the drive in any given time should be 0V (balanced). To generate such an signal, a special 'balanced' amp is needed. Yes, the sound quality of balanced 'phone + amp is much better than normal 'phone, and no, balanced 'phone require recable of normal 'phone so separate drive (on both side) can carry individual signal (as typical 'phone share a common ground, but balanced 'phone isn't)
Balanced connections are a favorite of pro's and recording studios. Many people feel the connections are more quiet than single ended for long runs of cable.

Umm. The signal wire in a single-ended system carries voltages that are both positive and negative as referenced to ground. Just like hot vs. neutral on the wall socket.
