That iEMatch is a very strange beast. (I have one.) It puts a resistor in parallel with your headphones, which lowers the effective z-out of anything that gets connected, but then one in series to reduce hiss/increase usable dynamic range. So it definitely DOES change the sound of low-impedance headphones. How they should probably advertise it is - once you're accustomed to the sound from the iEMatch+your_favorite_headphones, that sound won't change much as a function of z-out from various DAPs. It's clever, but not an ideal solution, IMHO.
Agreed. I haven't had much experience with it, I have
Weirdly enough, I also have the Mojo... how convenient, eh! I've not made detailed comparisons between the Mojo and V30, but since getting the V30 I can't remember the last time I used the Chord. Objectively I don't think the Mojo's technical superiority is in question, but in reality the difference is so small that the extra faffing around with yet another device in the chain simply isn't worth it.
...Ya looking to sell the Mojo?
