i think there should be a 7125a and a 7125b

or a 990a and a 990b

a- haveing the balanced input
b- with out

That way if someone wants to use them they can match it up.

if the concern is to save money and not include it on the 7125 why not save that same money on the 990 for users of the 7125.

comeone how big are your rooms that you even need more then 125 watts 8ohm or 190 watts 4ohms anyway?
