just joined and have probably idiot status with first question. i have a dspax620 and.love it but. i cant seem to balance it all. think i might have unusual rears for set up. ihave b and w 603s series3 as mains and kef cresta floorstanders as rears. but need to be on about -9db on rears otherwise they over power front chanels. but doing so i have to crank up the volume to -20db or more to get fronts to move.could be normal. but thinking about getting a pair of dm600s3s as i can move out of the way so they dont burst the ears.
