I completely agree. I absolutely love the LA remake and the soundtrack is such a wonderful highlight. The arrangements with the small woodwind/string ensemble are so playful, and you can tell that Ryo Nagamatsu really respected the original soundtrack when rearranging it. It's one of my favorite remake osts ever.
Fire Emblem Echoes has an ost I think is similarly excellent, but in a somewhat different way. It breathes life into many of the original NES tracks by orchestrating them, but the composer also included his own musical identity with the main "Echoes" motif, and he really expanded some of the compositions (especially for late game stuff and cutscenes)
