FiiO BTR7 OPEN BOX UNIT. Good condition, some marks on packaging, complete, 1 year warranty. 2 options, same BTR7 unit but for wired use, choose either an iphone lightning cable or usb c-c cable. FiiO BTR7 features the ES9219C in each of the left and right channels, which is paired with a low-pass filter and an amplifier in a highly-optimized audio architecture that captures every last detail and dynamics in your music. And with support for MQA, your music will definitely come across clearly and boldly. In terms of the amp structure, the BTR7 is the first portable Bluetooth amplifier to utilize 2 of the THX AAA-28 amplifiers. The FiiO R&D team had a breakthrough and was able to fit 4 channels of the THX AAA amplifiers into a compact body for a fully balanced audio design – resulting in 88% more single-ended power output and 30% more balanced power output compared to previous designs. Experience an extraordinarily bold symphony of music with the BTR7. For Bluetooth DAC/Amps, a high-quality DAC makes great sense. The Qualcomm QCC5124 Bluetooth chip adopted in the FiiO BTR7, with its dual DSP and dual-core CPU architecture, not only ensures stable connections but also supports both high-res formats like LDAC/aptX HD/aptX Adaptive and more common formats like SBC.
