LCD 2C closed back. Best portable amp

Hello. I just purchased my first pair of planar magnetics. I got the Audeze LCD 2C closed back version. I have a Fiio A3 portable amp. Is there a better portable amp I can use with these? Thanks!

Hello,
What is your budget what you would spend?

You will definitely want something stout. They aren’t really that hard to drive but the do better with sub bass when you have more power on tap. I would say anything with at least 1w.
