Got my iSine 20 on last farther's day sale. I got the bundle version with Cipher V2 cable, which I hardly use. I do like the Cipher cable but only used it when traveling light. I primarily use a regular cable with iFi Black label DAC with my sources daily basis. This is my ultimate mobile combo with iSine 20. I have not been touching my Shure SE846 since. BTW: regarding the hooks. I only managed to break only one hook since I got the 20. I never removed it and using it daily basis. I email the tech support, they actually sent me the new complete hook set free of charge. I also purchased additional set from Audeze. I think, I will be all set with the hook for a long while.
