ooo how did it sound after?
i thought UM's website said that they offered up to 8 drivers for SM3 V2 hahahaha
you are right, i just checked their site again. i guess my retailer just offered up to +3 drivers. but the +8 driver prices are way too much imo - one can get a full pledge custom for that price.
as for the sound department, the mids are now a tad smoother, more forward too. treble seems a bit more livelier. the bass department sounds the same
