Yes, the N3 has the ability to wake up with 4.4mm from the 1A. The nicely detailed and relatively neutral output of the 1A goes a way to slightly subdue the N3 lower midrange emphasis. IMO The 1A definitely doesn’t add any lower midrange to the N3.....even though the 1A could be considered slightly warm. IMO The XBA-N3 scaling ability allows the N3 with the 1A to open up, which is what the N3 needs. IMO Be sure to note the 1A will be very subdued and flat sounding with 0 hours out of the box. I seemed to notice the biggest change from 0 to 50 hours. Then a big improvement at 100 hours. Sony says it’s not totally ready till 200 hours. They continue to improve after that. Someone on this thread has 7000 hours on theirs. Pretty sure the N3 is the thickest sounding IEM I own? It has more bass in the lower mids than the XBA-Z5 and IER-Z1R.
