Grettings, Actual configuration (Beolink Multiroom + Possibility of adjusting each speaker individually which is not currently possible with a B&O device - except Beocenter4 or.... THE BSTH): Beosound Core (With Rega P3 connected) - Toslink - Almando SoundCenter Surround - BL11 + BL3 (Front L+R) +  BL3 (Rear L+R) Expected configuration (Beolink Multiroom + Possibility of adjusting each speaker individually which is not currently possible with a B&O device - except Beocenter4 or.... THE BSTH + Mozart): Beoconnect Core (With Rega P3 connected) - ?????? - Almando SoundCenter Surround - BL11 + BL3 (Front L+R) +  BL3 (Rear L+R) As there is (unfortunately) no more Toslink on the Beoconnect Core, to connect it to the Almando SoundCenter Surround, is it possible/preferable to use :

1. Hdmi port of the Beoconnect Core - Hdmi cable - Hdmi port of the Almando SCS ?
2. Usb-c port of the Beoconnect Core - Usb-C/Toslink converter - Toslink of the Almando SCS ? If yes... Do you know a good converter ?
3. Usb-c port of the Beoconnect Core - ?????? - ?????? of the Almando SCS ?
4. Powerlink RJ of the Beoconnect Core - Powerlink RJ to Powerlink DIN cable - Powerlink DIN of the Almando SCS (I've tried with the existing Beosound Core... but the sound is far less better than with the Toslink... Maybe a question of setting on the core but I've not found how to set "line" for "speakers connected"...

Thank you in advance for your help, your possible solutions and I apologize for my imperfect English... I'm French and no longer have the opportunity to practice Shakespeare's language on a regular basis... Best regards Ø
