Bluetooth 2.1 receiver for self-powered speakers

[TLEDDY]

Part One:
In my dining room I have a pair of JBL 305s using a Bluetooth receiver, signal provided by an Apple laptop. I want to add a powered sub via Bluetooth.

Is there a 2.1 Bluetooth receiver that will meet the need?

Part Two:
A similar question… How to set up Bluetooth using Passive speakers for mains and a powered subwoofer; ie. the Bluetooth receiver unit would have an internal +/- 100watt stereo amp and a variable output to a powered subwoofer.

And finally, is there a version of Bluetooth that is true high fidelity?

Thanks in advance to all the Wizards Herron!

A WiiM Amp/Amp Pro/Amp Ultra would do the job.

Supports Bluetooth, but also lossless Streaming.

And finally, is there a version of Bluetooth that is true high fidelity?

aptX Lossless exists, but it's fairly new and there are few supporting devices.
