Time to give the HiBY FD5 a mention and a proper thread.
More info on this DAC/AMP here: HiBy FD5 — Cyberpunk desktop HiFi
In reviews the FD5 is mainly praised for its musicality and dynamics.
(Just) coming from a FiiO K7, which has given me countless hours of joy, I can only attest to this.
The FD5 opens up and intensifies music for me.
The class A mode adds in my view what I would describe as complete “lushness”, while the class AB mode tones that down a little bit giving a tad more clarity and retains a little rawness (that some songs from e.g. U2 need in my view).
Maybe others can also share their experiences here?
