4.What's the main difference compairing BTR5 to BTR3 and BTR1?

1. Inside the BTR5 are two dual DAC--ES9218Ps, with both 3.5mm single-ended and 2.5mm balanced dual interface output. One DAC operates at single-ended, and one DAC is responsible for one channel at balanced-ended.
2. The BTR5 is equipped with a 0.49-inch OLED display, which can display the volume, power, encoding format, etc., and we can control EQ, filter, gain switching, charging switch, etc. through the display.
3. The BTR5 also made a leap-forward upgrade in USB DAC decoding. With a separate XMOS xUF208 decoder chip inside it, the BTR5 enables USB DAC to support 384K 32bit/DSD256, which can be comparable to desktop decoder.
