Amp recommendations for Hifiman Sundara?

I recently got some Hifiman Sundaras and while I’m loving them so far, I can definitely feel the need for an amp compared to my other, non-planar, headphones. I know planars are typically harder to run than dynamics. Does anyone have recommendations for amps that pair well with them? This will be my first headphone amp and I’m not planning on it leaving the house so portability isn’t a huge concern of mine but I am a bit limited on desk space so something on the smaller side would be preferable for sure. Budget would preferably be ~$250 or less.

I don’t have too much left to ask to get this post to the length this sub wants so I’m just stretching word count down here lol, thanks in advance
