Sounds very similar to my Rhapsodio hybrid with fuller mids, better bass response, they're very much an akin gene pool with little bit of Altone200 thrown in imo. I think the main differences with A83 and my RDB Mini (Rhapsodio) is A83 has an edge in detail extension, so you get that extra bite in vocals and overall detail around the mid-range hearing deeper into a sample. I already looked up places to buy lol however I need to convince myself pretty firmly I need it when I have Altone, H-300 and RDB Mini. As they're all very similar sounding hybrids, similar tonality, mid-range weight, treble. If it was going to be my first IEM purchase I'd take them without a doubt. Mighty fine effort here from Fidue, punches well on and above its price imo. What tips do you use Brooko? Heir tips work a treat for me.
