Got my Miracles back from refit... in time period when Miracles was on refit I bought TWcu3 cable for them, with this cable my Miracles now sound totally different compared to my Merlins paired with TWag2 Gold cable: compared to Merlins, Miracles now sounds muuuuuch darker on mid and high freaquancies, have more bass (especially midbass), but still in terms of naturalness I like bass of Merlins much better, in this term bass of Merlins closer to bass of SR-009, than bass in Miracles... main problem of bass in Miracles IMO is it's "heterogeneous" structure, with TWcu3 it's became better than with stock, TWag2 Gold and TWcu2 cables, but it's still "heterogeneous" compared to Merlins and (of course) SR-009...
Still overall I like Miracles more than Merlins, but if Miracles would have bass of Merlins, then they will be close to ideal sound for me in IEM form factor... but as they are, both of this models have their own pros and cons for me...
