Link? Besides, 900+ kbps in TWM is just not possible unless QHS (Qualcomm High Speed Link) is used. And this requires newer Snapdragon devices(AFAIK 855 is too old, not quite sure about 865 and 888). Maybe they will release transmitter with LDAC and QHS in future, but that's probably months (if not years) away.QCC5141 platform now has LDAC codec working and some products have it since mid 2022 (source: 52bluetooth). I hope FiiO can test and release an update to fix LHDC and add LDAC. If this become true, then FiiO will have the best product with triple Hi-Fi codecs.
FW5 doesn't have LDAC as well. They will probably release both of them at the same time (or close, at least).It is an old product in their catalog and they would rather you buy newer products.
