I have a Mytek Brooklyn....
I think it will sound different, in large part due to the Ayre diamond output stage. Also, and I'm not sure it's the same issue, I've had the Mytek shoot up to 11 upon static shock, so I would never again run it straight into the amps.
I will say that any loss of transparency varies a great deal on the pre. I would not in this case say you will find it better or not, but I do think you'll find it revealing of how the Ayre sounds. :)
Please try it and let US know instead.
Best,
Erik
