Dear Mr. Shao,
the Power I has more unbalanced inputs than balanced input. Due to that we designed the POWER I as an unbalanced unit. The balanced input are not fully balanced but generated with a transformer and premium ICs from Burr Brown. So, the quality of the balanced inputs are very very close to a fully balanced design.
