Interest list for LL1684 PCB:
1. NicMac, 1 set of LL1684 PCBs (possibly also the transformers)
(not sure if I understood correctly that we should start a list here - I also send a PM)
Same problem with me, didn't know where to add my name, if here or in the dac GR. I will add it here too then:

I'm back from the recording studio.
I confirm, after replacing the lmv7219 and the addition of the 0.1uF capacitor, the excellent locking of AES/EBU input up to 192kHz.
You say the original lmv7219 is not good ?
yes, this file!
thanks
Also the ground should be connected in a different way

Please tell us wich way then .

Pin 1 on XLR connects directly to chassis - always.
Pin 2 = + hot transformer
Pin 3 = - cold transformer
Let the secondary of transformer 'float'.

thanks but I am not sure I understand that Square painting marked XLR and RCA.
I have tested bandwith with lundall ll1684 and 2,2uF Jantzen +10k to ground.
Input 192khz coax, output 47k resistor.
8Hz to 35kHz +/-0.2dB
Nice, if you add 10uf it will probably go lower.
Yes, see this postYou say the original lmv7219 is not good ?
Was not stupid when I bought this after all

Mundorf MKP is not stupid
I still need to play around with different caps and bypass caps with the LL1684.

After replacement of the comparators every input configuration and every cable previously used works fine, from 32khz to 192khz.
Do you want a jump to leave separated the ground of output ?
