Absolutely, that is what seemed really weird to me.. and certainly that would make the most sense, and I can't say I took the simple step of removing the bsc to compare. (I wonder if I screwed up the wiring on the bsc and somehow got something swapped around) I will do that and see what it sounds like.
And yes the soundstage with these is actually quite good, I have always thought the fostex speakers beamed too much and always preferred my Straight 8's but in this configuration they really setup a sound stage as nice as the S8's.
