Seeking feedback on a “DAC Preamps with Bluetooth Input/Output” – Is there a need for this?

[westfanbb]

Hello, ASR community. I am currently wondering a DAC preamplifier with Bluetooth as its primary input/output interface, and I would appreciate some objective feedback on its practicality and market viability.
Product Concept: A high-performance desktop DAC/preamplifier that uses Bluetooth as its primary input/output interface, supporting two specific signal paths: Bluetooth Receive Mode: Bluetooth input (LDAC/aptX Lossless) → High-end DAC (e.g., ES9039MSPRO) → RCA/XLR output. Bluetooth as an output mode: RCA/XLR analog input → High-quality ADC → Bluetooth output to headphones/Bluetooth speakers. Reason for Asking: Most mainstream DACs only offer Bluetooth “receiving” functionality.

Are there specific practical use cases for this design?
Are there similar products currently available on the market?
I look forward to your insights, grounded in “scientific evidence,” to analyze whether this is a useful tool or just another unnecessary box on the desk.

I have a very specific use case for the Bluetooth output mode, but I'm not sure I'd actually spend money to fulfill it. My stereo system lacks a headphone output and is rather far from comfortable seats. The device you describe would allow me to listen to it with a pair of wireless headphones.
