Rod Rain Audio B9 Bluetooth6.2 Multifunctional Lossless Audio Decoder ES9039Q2M HiFi Headphone Amplifier

Differences:
- Standard version: adopting 2068 operational amplifier or NE5532 operational amplifier (in random).
- 1612 Op Amp version: adopting 2pcs OPA1612 operational amplifiers.
- 8620 Op Amp version: adopting 2pcs AD8620AR operational amplifiers.

Highlights:
- Built in original ES9039Q2M chip, with first-class performance and built-in capabilities.
- Specially upgraded solid-state IC relay, faster and better performance than electromagnetic relay.
- Adopting for SITIME solid-state high-precision silicon crystal oscillator, it has stronger indicators than domestic gold crystal oscillators, and its jitter index is comparable to femtosecond.
- Added 4.4 balanced and 3.5 single ended output interfaces for higher headphone compatibility.
- For Qualcomm Bluetooth chips support all mainstream Bluetooth formats currently available.
- Built in positive and negative dual 15V boost, operational amplifiers work more stably and perform better.
