The FiiO BTR1 is a Bluetooth receiver with an integrated DAC. It is intended to give user, the listener, a more refined, detailed, articulate, and sonically pleasing experience when listening to music over Bluetooth. Quite often, Bluetooth streaming leaves something to be desired—music can sound tinier, thinner, and describable with other pejorative adjectives. At the center of the BTR1 is the AK4376 DAC, which handles sample rates and resolutions up to 384 kHz / 32-bit. This DAC is housed alongside FiiO’s Bluetooth Chip architecture to provide support for Bluetooth 4.2, as well as Bluetooth aptX and SBC.
