Moondrop Blessing2 + Spinfit W1 tips + balanced modular cable + Fiio BTR3K
This setup is comfortable and secure in my ears all day long & sounds great on the 2.5mm balanced port of the btr3k. I usually keep in it LDAC or APTX-Hd and its basically indistinguishable from lossless. Plenty of power and an overall pleasing sound signature thanks for the AKM dac.
I have the exact same setup, and while I get the itch to upgrade every now and then, I just can't justify the cost given the performance I get out of the B2 and the BTR3K.
facts the next step up would be something like the variations but you would be getting into heavy diminishing returns
