By tight I mean precision in timings of multiple instruments/sounds relative to each other.
My hypothesis is as the title of the thread states: Bigger soundstage means less tight musically.
My rationale is that the relative perceived distances from the ear of different sounds affect the perception of timing of those sounds due to when the sound is perceived. i.e. if two sounds are produced simultaneously but one sound is perceived to be relatively further away then the latter will be perceived as occuring earlier.
E.g. If a guitar is strummed at the same time as a snare drum is hit, but the guitar appears deeper (within the soundstage) than the snare drum then the snare drum will be perceived first.
Thus a tight recording will sound tighter the smaller the soundstage.
This isn't completely speculative wondering; it is an explanation for the phenomenom I've noticed that tight recordings actually (seem to) sound tighter (to me with my gear) when the soundstage is smaller.
