RE: Is Parasound A21 a true balanced design?

Hi Steve,

I suppose that I deducted it from the following:

1) Despite several very favorable reviews describing the A21's circuitry in detail (another review attached), there is never any reference to differentially-balanced design (even on Parasound's website).
2) The only description of the XLR circuitry in the reviews and on Parasound's website is "Balanced inputs with discrete circuits and XLR connectors ". The RCA outputs also have their own discrete circuit - Is this possible in a true differentially-balanced design?
3) The above picture shows that the L/R circuitry is not symmetrical as it is in my fully-differentially-balanced Krell amp.
4) I am not aware of any true differentially balanced amp that sells for $2k as it is very expensive to execute.

Obviously, I could be wrong. What is your take on the picture?
