Best cheap(ish) amp & dac to get?

[eevee047]

Recently bought a pair of custom one pro's as an upgrade to my crossfade lp2's, wondering what amd&dac to get to go with them, my budget is up to £100 ($156), preferably available in england, I already imported these beyers and the import tax and other charges are absurd, so no shiit or mayflowers, unless they add tax on to the order. Also I was unsure whether a tube amplifier would be better or not, I do slightly prefer the "funner" tone of the lp2's. I listen to techno, trance, other electronic genre's, melodic death metal, rock and some piano music. Thanks for any advice

FiiO E10K is inexpensive at around 75usd.

I checked out the e10k, it seems to emphasize bass quite a bit. And with that, coupled with the already somewhat bassy custom one pro's im slightly worried it could be overpowering. Am I being paranoid? or are there any other amp & dac units you recommend? thanks
