Apple just updated AirPod Pro to accept high bit rate audio, but I don’t think that most Apple devices will transmit high bit rate via Bluetooth. Someone here will know the answer and I believe this is one reason that the post above discusses DAC dongles.
I think that a reasonable question would be at what price level can I purchase a used DAC that clearly outperforms computer streaming? I suspect that the answer is well under $1K. The next threshold for me would be at what spending level will allow me to hear improvements as I upgrade my other components? Another question might be, if I spend $5000 on a DAC and other upgrades to my present system, what components should I buy on the used market. The best approach to all these questions is to post your system on your profile so that others can quickly see what you are using. I know that you listed components in your original post.
Here is a discussion regarding posting your equipment on your profile….
BTW.. I have a family plan with Quboz and everyone can stream on their phones and in the car. The family plan is not much more than the single license and allows for streaming in high bitrate, or low bitrate similar to other streaming services. No, I can’t stream just using my watch like I can with Apple.
