Ok, you have an ADAM A7 pair.
But… what about the acoustic of your room?
Is it perfectly OK?
I have an Opal Event pair and the HD-25 + the HD 650. They are all independantly awesome. But as my room is not treated, I cannot compare them.

The only thing I know is that for my mixes, I starts to listening on my Opal pair and then after on the HD-25 or HD-650 for details.
And in that way, I’m happy with my mixes and masterings:
