kyyuan, I think 8' is too wide. I used to think 8' was great - great width, depth,..... but I then moved them to 6' width, and moved my listening chair to 10' back with the alignment to the ears via the alignment gig/tool; wow........ The stage increased all around, width, depth, height, - in fact the soundstage is the widest it has ever been (depending on the recording - say a good symphony, let alone Miles KOB, a 13'-15' wide stage is regular here). With the older SE's no less (not MX's). the air of the soundstage engulfs me as well (not like a wall of sound you are seperate from, but rather included in). Better bass this way too, with centerfill, palpable players well outside the speakers, great rear corner depth(with the seating position moved back to 10') Now, I use a Joule Pre and Blue Circle amps, both through huge soundstages as well (in addition the Merlins setup well and room treated with RoomTunes). I couldn't believe it, but what the Merlins seem to do is throw a circular sound bubble - 6' apart with your seat 8-10' back, allows the stage to come together in a more complete manner, walls dissappear, as well as allows the sound to become more full/complete as well. They are not nearfield small room speakers imho.
