well, i own a SR4300, and now i combined it with an int. amp (Pioneer A402) so that Pioneer just drive the front channel Mission floorstander, but i noticed out a weird problem during the test tone, the left channel tends to sounds louder than the right channel, i need to set the db level on right channel to +3 then only can match the left channel volume at 0db...what's happening, i tried two interconnect cables from marantz pre-out to the pioneer line-in...also the same problems....
when i plug back the front speaker to the Marantz, everything seems fine, the problem only occur when i use the pre-out function, any ideas?
