I am looking to get either a DB750 or DB359. I'm wondering, how do the two compare to each other? What kind of tonal differences are their from the 359 to the 750? Also, would I be able to power two GS210s, or a GS410, or GS210 and GS115, or GS210 and GS212 together using only the DB359? Would that be loud or quiet? And in comparisson to the 750, would it be equally as loud? Also, on the DB359, if I wanted to use it for studio purposes, if I turn the unit on, and keep the standby off, with the Balanced output still work? Same question for the DB750.
