Play simultaneously on wired speakers and Bluetooth

Hi,
For now the Amp Pro can only play on wires speakers OR Bluetooth speaker alternatively but not simultaneously (selecting 2 outputs at the same time).
Would be very nice to be able to do that.
Many thanks

I've bought a WiiM Mini to connect my Klipsch the Three Plus speaker as a rear left speaker.

OMG, what a hassle, clutter and expenses.
When I connect the WiiM Mini, a lot of noise comes out of the speaker. It seems that I have to buy a iFi Defender + usb isolator to stop the ground loop. The WiiM Mini is almost €100, the iFi Defender is €65.
The puck, usb power cable, toslink cable bring clutter to my space
The automatic sync doesn't make the music in sync, so I have to do it manually. But a while later it's out of sync again.
I saw that the WiiM Mini has a weak WiFi signal.
My Klipsch speaker is in open space just 4 meters from my WiiM Amp Pro. And in excellent Bluetooth range.

I wish it was possible to just connect my Klipsch the Three Plus speaker with Bluetooth. It would save me a lot of hassle (no ground loop noise troubleshooting), a lot of money, and physical clutter.

This case is an extra reason to add support for using Bluetooth speakers as fill speaker, surround speaker or (near) multiroom speaker. I hope it comes very soon!

Why all this hassle while it could be simple?

To be honest, where you have options in this situation like using the Mini’s optical output into the speaker’s optical input, I’d avoid Bluetooth like the plague.

Also, using Bluetooth speakers for surround sound as you suggest would be fraught with issues - WiFi is a much better transport for such use

Thanks for your perspective! I totally agree that WiFi is technically the superior transport for high-bandwidth, multi-room audio. However, in this specific 'fill-speaker' scenario, I believe Bluetooth (specifically 5.x) is being overlooked. Here is why it is a robust technical solution for my setup (and those of others facing similar ground loop or network challenges):

  1. Galvanic Isolation: My biggest hurdle with the WiiM Mini is the ground loop noise caused by the shared power/audio ground when using the Klipsch USB port. Bluetooth provides 100% galvanic isolation by design. No copper connection means zero electrical noise, solving the issue without needing expensive isolators like an iFi iDefender.
  2. Predictable Latency vs. WiFi Jitter: While Bluetooth has inherent latency, modern 5.x implementations are remarkably stable at a 4-meter line-of-sight distance. Since WiiM already has a 'Sync' slider, compensating for a fixed offset is easy. In my case, the 'drift' I see on WiFi (fluctuating between 20ms and 30ms due to local interference) is actually more problematic than a slightly higher, but constant Bluetooth delay.
  3. Bluetooth 5.x Robustness: Modern Bluetooth 5.x uses Adaptive Frequency Hopping (AFH), which is excellent at avoiding the exact WiFi interference that is currently weakening my Mini’s signal. At this short range, a direct 5.x link is often more robust than a WiFi hop through a distant router or congested mesh node.
  4. Empirical Stability: In my specific environment, I have used Bluetooth speakers in this exact spot for years without a single drop-out or sync issue. It's a proven solution for this distance.
I’m not looking to replace WiFi for Hi-Res multiroom, but as a 'convenience' option for fill-speakers, Bluetooth would eliminate the clutter, the cost of isolators, and the sync-drift I'm currently experiencing. It would be a great 'problem-solver' feature for challenging electrical or network environments! I hope the WiiM Team will add this feature in the near future.
