Though we don't quite agree with IEMatch to have an adverse impact on the sound, thank you for your review. Nice work!
As for IEMatch itself, this is an option for customers to decide whether it works for them.
Also, please do check this thread, iEMatch is explained in detail there:

I'm thinking my experience with the nano's iematch is due to the output impedance and the Andromeda. As for the dongle, I think it is a much better fit. Any change in sound isn't as noticeable, and certainly not while on the go. I use it every day.
I also have a review of the micro black label on the way. So far these are great products!!
