Vega with the right tips and right source can hold against multi-BA CIEMs, but you have to have the right combo. Wish Vega wasn't too picky with source and ear tips.
It's not a matter of Dynamic vs Balanced Armature.
Two IEMs with the same number of BAs can possess vastly different soundstage dimensions. It's really all in the tuning.
