Diffirent between Parasound 2200 and Mark ll

[pwgtang]

Hello, I recently bought a used Parasound 2200 power amplifier,
can any one tell me what was main diffrent between 2200 and
2200 ll. Because I heard some late produce 2200 are the same
as mark ll. May be some one can tell from the serial No.Thanks.

Possibly slightly difference in term of component selection.
